My Half-Price Valentine

One little mystery, two sworn enemies, and a big, heart-shaped box of chocolates. Love conquers all when the valentines are half price.
Annalise Winston left Cardinal Point years ago with a bad attitude and an even worse reputation. She never expected to be welcomed back with open arms, but she also didn't think someone would shoot at her parked car and vandalize the animal shelter she has come to save from financial ruin. Is it really personal? Or just a coincidence the attacks seem directed at both her and her important mission at the shelter?
Shane Calfee loves his job as co-owner of Cardinal Point Security Services, but lately, the long hours and lack of sleep are getting to him. Especially since his mom still pressures him to run the family furniture store instead of pursuing his dream to move up to other jobs in law enforcement. To top it all, his best friend's ex-girlfriend, Annalise, is back in town and in danger. How is it he's the one who happens to be around when she needs him? And why does that feel so good when it should be oh, so bad?
