Ymir’s Tears by Julie Mannino

Luca

Luca figures he must have hit his head pretty hard when he fell down the stairs. After all, why would there be a watery chamber with a giant tear in the basement of an abandoned sanatorium? He also shouldn’t be glowing gold or inviting a homeless man to live in his room.
He doesn’t expect his new, stunningly hot roommate to be a Norse god or for Asgardians to snatch them both one night. Thor says the golden glow means Luca is slowly turning into an Asgardian since he found Ymir’s Tears. If he’ll help the Asgardians get into that mysterious chamber, they’ll give him a place to stay and forgive him for harboring a dangerous murderer. But did Loki have a good reason for his crime, or is he selfish, foul, and dangerous like Thor says?
