The Skin She’s In by Margo Bond Collins

Capturing the killer who was stalking the shapeshifter community should have earned weresnake Lindi Parker and her new boyfriend, mongoose-shifter Kade Nevala, a vacation. Instead it earned them a basket of baby lamias and a whole pile of trouble.
Some shifters think no lamia should be left alive. In fact, a faction of shifters led by one particular werewolf pack is determined to take Lindi down any way they can.
Kade and Lindi must use every skill they have to make sure lamias aren’t wiped out of existence again.
But winning might cost them everything.
