The Musician and the Monster by Jenya Keefe

Hatred is a spell only true love can break.

Ángel Cruz is a dedicated session musician, until loyalty to his estranged family forces him to work for Oberon: the feared and hated envoy from the Otherworld. Overnight, Ángel is taken from his life, his friends, his work, and trapped in a hideous mansion in the middle of nowhere, under constant surveillance, and with only the frightening fae for company.

Oberon’s poor understanding of humans combined with Ángel’s resentment and loneliness threaten to cause real harm to the pair. Then a long winter together in the mansion unites them in their love of music. Slowly, Ángel’s anger thaws, and he begins to realize that Oberon feels alone too.

Gradually, these two souls from different worlds form a connection like none other. But hate and prejudice are powerful things, and it’ll take all the magic of their love to stop the wider world from forcing them apart.
