I M P U L S E | Jackson Whittemore 
**Sequel to Instinct
Her message was clear. Annie was leaving, and she had no plans of returning... which was reasonable to her friends considering the past events that had shaken each of them to their core. After promising never to call Annie unless of an emergency, one day... Annie gets a call.
A powerful and evil entity named the Darach has taken Melissa, Chris, Sheriff, and Sam hostage and will be killing them in less than 72 hours.
Returning home, Annie, Allison, Stiles, and Scott use an ancient ritual to find their loved ones, reigniting a beacon called the Nemeton in their process.
While Scott struggles to find his place as an Alpha, he, Allison, Annie, and Stiles begin to experience strange side effects as a result of reigniting the power within Beacon Hills. And just when Annie believes she's escaped her past, someone unexpected shows up and changes all of her plans.
Battling through tragedy, heartbreak, defiance, hatred, love, and lies... the Pack takes on their biggest enemy yet.
And it's scarier than anything they could ever imagine.
