Under Her Skin (Lindi Parker, Shifter Shield Book 1)

She's lucky he's a charmer. He's lucky she doesn't bite. Much...
Lindi Parker works hard at being human, not an easy task for a snake shifter. She has no desire to search for others like her--until a new case changes everything. When Lindi learns she's not the only shapeshifter in the world, she also realizes she might be next on a killer's list.
In order to save herself and the abused children she works with, she will have to team up with Dr. Kade Nevala, a member of the shifter tribe responsible for eradicating weresnakes--and the most attractive man Lindi's ever met. Even more terrifying, she'll need to embrace her serpent side, a choice that has enormous consequences for Lindi, and for everyone around her.
