Deadly Nightshade — Lynnie Purcell

Julie Aim knows four things: life is never fair, rules are for people not clever enough to circumvent them, she's awesome at fighting shades, and nothing lasts forever.

A month after her fight with the dragon, Julie tries to go to a Halloween party only to be inconveniently captured and forced to hunt a shade against her will. It's only the beginning of trouble, and she must depend on her friends, and Sully, to save her before it's too late.

‘Deadly Nightshade' is the second book of the Dreamer Chronicles series.
