Siren Song: Heartstrings

Arabella "Bella" Jewel Martin hasn't seen Beacon Hills-or her twin sister Lydia-in six years. When their parents divorced, ten-year-old Bella made the ultimate sacrifice: she went with their father to Los Angeles so Lydia could stay with their mother in the only home they'd ever known. Now, at fifteen, Bella's father is relocating to Seattle for work, and there's no room for her in his new life. With nowhere else to go, Bella returns to Beacon Hills on the eve of sophomore year, walking back into a life she left behind and a sister she barely knows anymore.
She has no idea that Beacon Hills harbors dark secrets, or that her return coincides with something ancient and dangerous awakening in the woods. She doesn't know about werewolves, hunters, or the supernatural world lurking beneath the town's perfect surface.
And she definitely doesn't know that she's about to meet a hyperactive boy named Stiles Stilinski who will turn her carefully controlled world upside down.
But first, she has to survive her first night back home.
