I can't find the book I had years ago on this app.. it was an AMAZING book, small description below! PLEASE HELP ME FIND IT!

Was based on Greek god and he was on earth and met this woman. she invited him to crash the night. She fancied him a lot but did not know where he care from. As they began to get along she felt for him (can remember something about confession in a kitchen. Idk). After time he confessed who he was and that he could rerun to his city while he sleeps (idk if this was because he was banished or something).  He then took her to the place in his dreams and she got kidnapped by other Greek gods who were evil. 

Some names I can remember: 
Zeus 
Prometheus

that's all I can remember. Please help!
