Newly Undead in Dark River by Grace McGinty

Welcome to Dark River. Population 0.
When Mika McKellen woke up in a stormwater drain while backpacking around Canada, she knew that her mother was right. If you made bad choices, you would end up dead in a ditch. But when she stumbled into Dark River, even her mother could never have dreamed up the residents of this small town in the middle of nowhere, Alberta.
Oh, it had all the usual suspects. Quirky diner owners, untrustworthy outcasts and a Sheriff so hot he’d make any red-blooded woman with a heartbeat beg to be in cuffs in the back of his patrol vehicle. No, the really unusual thing about Dark River was that it was entirely populated by the Undead. Vampires to be specific. And so was Mika.
As Mika adjusts to the life of a Vampire, a dark presence stalks her from the shadows. One of the residents of Dark River was her maker and her murderer.
And they were determined to ensure that Mika never rested in peace.
