The Venom in the Valentine — Shea MacLeod

Viola Roberts is down in the dumps after discovering her boyfriend, Lucas, is snowed in back east. Her best friend, Cheryl, agrees to substitute a girls' weekend for the romantic Valentine's Day he had planned. Massages and mani-pedis for the win! That is, until the hotel guests start receiving venomous Valentines, and one of them ends up dead. In a remote resort on the wild Oregon coast, it's up to Viola to get to the bottom of things before any more guests fall to the killer's poison pen.
