Summer’s Savior by Joy Wild

Summer Love is a paramedic student who works at the local church as a bookkeeper while she finishes her schooling. When she finds a major accounting discrepancy with a huge donation, she does all the right things, making sure the evidence is secured and involving the local police. But, when the woman who made the latest big donation shows up dead, she is forced to realize this is bigger than just small time embezzlement from the coffers.
Samuel Saint, detective with the fraud division the of Louisiana State Police is assigned to Summer’s case—in more ways than one—and convinces her to go undercover with him at the church. As the body count piles, and attacks clearly meant to eliminate Summer become increasingly more deadly, Summer and Sam end up spending more time together than they expected. Feelings develop, and when Sam’s little secret is revealed, it threatens to tear apart everything they’ve started.
Will Summer be able to let go of her insecurities and trust Sam?
Can Sam prove to Summer he means every word he’s said from the moment they met, before the killer claims the next victim?
