Gluttony - Sin-Eaters, #1

An ancient sect of gods, known as Sin-Eaters, have one last chance to save humanity from an Emperor God bent on world domination. And it all begins with Gluttony. Tialoc had one mission, find gluttony and return it to the tlazolli or sin box. He doesn't expect to find the sin wrapped in a sexy chocolate-skinned woman or that she is his mate. CJ accepts a trip to paradise to meet Tialoc. When an accident sidelines her before their first date, she's hesitant to go at all.
What she isn't prepared for is the passion or love they share. When their lovemaking has unexpected consequences, time is of the essence. Tialoc must convince CJ to embrace her destiny or lose him forever.
