If Rachael Adair could only use one word to describe her life, it would be, "pandemonium." When her mother was diagnosed with non-Hodgkin's lymphoma, she knew life couldn't get any more complicated. As the disease sows discord amongst family members, Rachael is forced to deal with a classmate making her existence a living nightmare and cryptic threats from a little girl calling herself Delilah. All she can lean on are her new-found friends, Vera and Holden. Then Holden's guardian reveals their family secret: they are werewolves. And when her mother dies, their alpha intends to offer her a new life as a lycan. While our heroine labors to keep her head above water in day-to-day high school drama, the alpha's interest in her inadvertently signs Rachael's death sentence. Howl of the Sequoia is one girl's journey into the paranormal, a world she is utterly unprepared to confront, and where vengeance can be taken for the smallest perceived slight. Only when she has to fight to save her brother's life does Rachael realize what sort of monstrosity she's up against-and the consequences of becoming one of the pack.

Two years have passed since Rachael Adair was thrust into the world of lycans. And it's finally time for Aaron to make good on his promise. Jackson is back. But upon his return, little kids go missing. Many turn up dead. In Aaron's pack, a lycan who cannot control his rage must be put down. Rachael desperately wants to prove her brother's innocence, but it seems Aaron blocks her every move. And when she tries to turn to Holden for support, she finds he and Aaron are at each others' throats again. With the men trying to kill each other and her friends growing distant, will Rachael be able to find the proof she needs to keep Jackson from an old-fashioned lycan killing?

With Rachael's friend gone and her love lost, she doesn't quite know what to do with the pieces left behind. Her brother, Jackson, is determined to keep her at her side no matter the cost. Together they come up with the very compromise Holden swore he would take vengeance against: that Rachael becomes a lycan. But when she proposes the idea to the pack alpha, Aaron, he's surprisingly resistant. Then Holden shows up at her house with an assortment of new plans... all of them involving the death of his former alpha. Then Holden commits an unspeakable crime. Aaron and his pack scramble to defend themselves against their former ally. Rachael is torn between her old life and the promising new one lurking in the distance. She wants to become a lycan, but Aaron refuses to entertain the idea any longer and Holden has promised to kill her if she goes through with it. All of this culminates in a decades-awaited showdown between Aaron and his former charge, and it comes down to who Rachael places her loyalty in to: Holden, her first love, or Aaron, the alpha promising to keep her alive....
