Some time before the series began, Sorrel joined The Thirteen.
After winning the War Games, Manon and the Thirteen are sent with half the Ironteeth witches to Morath to assist Duke Perrington. After four weeks in Morath, Manon and the Thirteen become suspicious of the strange goings-on and are grating against Duke Perrington’s orders. Sorrel accompanies Manon to a meeting with the duke. On his order, Manon takes her Thirteen hunting for people living in areas near Morath. When Asterin questions Manon's choices regarding the duke's orders for Manon to choose a coven to be experimented on, Sorrel replaces Asterin as Second.
Manon and Sorrel visit the blacksmith at the war camp to examine the weapons he has been making for the witches. They discuss thee demotion of Asterin, and what the Blackbeak Matron is capable of. Sorrel tells Manon that more than anyone, Asterin has never forgotten for a second what the Matron is capable of.
After Manon's discussion with Duke Perrington at the war camp, she tells Sorrel and Asterin to ensure there is constant surveillance of the Blackbeak witches. Asterin wants to let the Yellowlegs and Bluebloods know about the danger, but Manon tells her they can only "tug so much at the leash."
Sorrel is with Manon and Asterin when Elide Lochan reports what is happening to the Yellowlegs. The witches are horrified by what Elide has seen. Asterin attacks Manon for giving the duke the Yellowlegs witches. Manon demotes her to Fourth, making Vesta Third. Sorrel is unwillingly prepared to kill Asterin if Manon orders it. Asterin is furious that Manon won't stand up to the Matron.
The Thirteen take Kaltain Rompier, Duke Perrington, and his men to a tribe in the White Fang Mountains and Kaltain tortures them with her shadowfire. Duke Perrington then has the Thirteen slaughter the tribe.
The Thirteen are meeting when they’re interrupted by a man with a Valg inside him. He attacks them with darkness and mental pain. Manon kills him while the human trapped inside, Roland Havilliard, begs for death. Manon looks on in horror at the effect that the Valg powers have on those among the Thirteen without golden eyes. Because Sorrel has gold in her eyes, she is among those unaffected.
When Asterin is telling Manon her story, she explains how Sorrel and Vesta helped save her life and come back stronger than ever.
Manon, Sorrel, Asterin, Vesta, Fallon, and Faline rescue Elide. The Thirteen barely escape the explosion caused by Kaltain that destroys one-third of Morath, which includes the destruction of the evidence of the Thirteen’s actions. The Thirteen drop Elide off in the Oakwald Forest and send her on way before returning to Morath. The Thirteen decide to stay at Morath until the Matron arrives and then they will decide what to do.
Sorrel is with Manon and the Thirteen as they tensely greet the Blackbeak Matron and her coven at Morath. The Thirteen are sent on a mission to take control of Rifthold and bring Dorian Havilliard, now king, to Erawan if he survives. They are also ordered to destroy the glass wall Aelin Galathynius made surrounding the palace. Before leaving for Rifthold, Manon tells the Thirteen not to let anyone kill Dorian. Sorrel participates in the sacking of Rifthold. She then attends Manon's trial for the death of five Yellowlegs witches.
Sorrel comes to get Manon for Asterin's execution. She tells Manon that Asterin is going to her death "to keep your secrets." It's the closest she's ever come to outright challenge or resentment. At Asterin's execution, she and the other Thirteen give Manon the gesture to honor a Witch Queen. When Manon refuses to kill Asterin and yells at the Thirteen to run, she grabs Asterin and the coven escapes on their wyverns.
The Thirteen arrive at the beach in Eyllwe and join in the battle against Maeve's armada. They help Rowan and the group win the battle. The Thirteen is reunited with Manon afterwards. Manon asks them if they heard the truth about her parentage and if they will still follow her. Asterin tells her that they will, and once again the Thirteen give her the gesture honoring a Witch Queen. Manon declares that they must become better than their foremothers. Manon, the Thirteen, and Dorian promise the group that they will find the third Wyrdkey and the Crochan witches to unite them to fight with Aelin.
For the past two months Manon, the Thirteen, and Dorian Havilliard have been hunting for the Crochan witches. They are currently in the White Fang Mountains. Manon is worried that Dorian might have to be the sacrifice to forge a new Lock. Dorian has been training with the Thirteen. They work on swordplay, archery, knife-work, and tracking. Sorrel gifts him a witch-knife the first time he managed to pin her.
The next day the group is preparing to move on when Manon is attacked by a mighty, white bear. Dorian freezes the creature with his magic and it shape-shifts into a Stygian spider. The spider is Cyrene, the spider who Manon encountered to get spidersilk for Abraxos’ wings. She tells Manon that she tracked her scent using her belongings left at Morath. She says that there are Crochan witches nearby.
Cyrene leads the group to the Crochan witches who greet them with mistrust. Glennis Crochan introduces herself as Manon’s great-grandmother. When two Yellowlegs covens attack, Manon, the Thirteen, and Dorian, help the Crochans kill them, which gains them some trust. Dorian realizes that Manon deliberately attracted the Yellowlegs to try and gain the Crochans’ trust. Manon and Dorian explain that they are there to ask the Crochans to fight against the Ironteeth witches and Erawan’s army.
Glennis tells her that only a Crochan Queen can summon them to war, and Manon has not been accepted. She says that they are on their way to Eyllwe to answer a call for aid by the southern hearths. The group and the Crochans are delayed for a week while they heal from the Yellowlegs attack. When the group is too late arrive in Eyllwe, Sorrel helps bury the dead, earring some more respect from the Crochans.
When the Thirteen and Manon go to the Ferian Gap to speak to the witches under Petrah Blueblood's command, Sorrel is there. Back at the Crochan camp, a Crochan scout reports that Terrasen has sent out a call for aid. Manon, as the Queen of the Crochans, spreads the Flame of War to call all Crochan witches to aid Terrasen in the fight against Morath.
Orynth readies for battle as the Ironteeth aerial force approaches, 1,000 strong. Fortunately, Manon arrives at the same time with the Thirteen and 5,000 Crochan witches. The surprise buys them a day. The next day during the battle, Abraxos is hurt and Manon is unable to stop the Thirteen as they sacrifice themselves by performing the Yielding in order to bring down the final witch tower before it can destroy the castle. Sorrel holds the way open for Asterin before she goes.
Sorrel was referred to as the stone to Manon's ice and Asterin's fire. The Blackbeak Matron has told Manon to make Sorrel her Second, as ice and stone were sometimes too similar. But Manon knew that Sorrel was grounded enough to even out both Manon's ice and Asterin's flame. This made Sorrel the perfect Third. A stolid and wise witch, she was extremely loyal but still willing to question something if she believed it was not right.
Though not as beautiful as the other witches, Manon remarked that she was "what mortals would consider pretty." She had tan skin, dark brown hair, thick, dark brows, and gold-flecked black eyes. Her physique was like that of a battering ram - compact, short, and strong.
