I adored The Mars House but—assuming you’ve not read Natasha Pulley before—might be better to start with one of her earlier books. She’s previously written literary historicals with a mild fantastic element and understated gay pining, whereas the Mars House is science-fiction, also with the understated gay pining, but also all in on her tendency to zigzag all over moral grey areas. I love her, she’s my favourite author, but she’s not traditional romance genre as such 🤷♀️
