Undeniable and Undone - Undone Series, #5

Rosemary Everspark, a witch who's been avoiding using magick since her elder sis and mother went down a dark path abusing their family's dark grimoire, must reawaken her powers to catch a killer and save the world from an apocalypse, all the while fighting her feelings for the irresistible vampire/demon-hunter Jesse Jackson. After her mother was murdered on Rose's ninth birthday by her vampire boyfriend, Rose develops a hatred for more than just dark magick; she despises bloodsucking vamps too! She most certainly won't allow herself to fall for one! .That is until he shows up and saves her sister from demonic possession and death.
It's more than their heated banter and his wicked grins that reel her in. It's the vividly erotic dreams of Jesse keeping Rose from a good night's sleep that interfere with her plan to not fall into his bed in reality. It's the flirting. It's the intense way he looks at her. If he'd just stop looking at her! And if she could just stay away instead of stalking him in the form of a black cat.While Rose would like to dismiss her feelings, a tarot card reading reveals an unsettling fate: Rose must die and be reborn.
She speculates she'll become the very thing she despises most: a vampire just like the one who killed her and Velda's mother. and that's if she survives the coming apocalypse requiring spilled Everspark blood. When Rose is captured by the serial killer vamp she's been hunting, Jesse rescues her, and unaware of her impending doom to save the world, feeds her his blood. When the end arrives, Rose sacrifices herself to save everyone using an undoing spell from the dark grimoire, thus destroying a demon her sister unleashed, stopping the apocalypse, and breaking all spells ever cast from the book. Rose is dragged into Hell and trapped in the collapsing dimension with a ghost who'd latched herself onto her.
Not only that, she's undead thanks to Jesse's blood! Now she must fight to survive and escape her soon-to-be-really-dead fate or wait to be saved. Either way, that's just the beginning.
