what do you mean what happens? it's right there on the cover, Alexander Le Himbo gets stuck inside an owl's eye and he's terrified so he can't sleep anymore

A man and an owl stare deeply into each others' souls until the man dies from lack of sleep 13 days in

I get really bad vibes from this cover for some reason, so I am going to guess that there is a subplot where a 47-year-old man cheats on his wife with a 19-year-old woman.

A person slowly turns into an owl, one fart at a time.

The owl is stalking a tiny man throughout the book that it thinks would be delicious.

The entire book is one of those semi abstract prestige TV intros like True Detective or House of Cards.

Dude tries to fuck an owl and barely survives the encounter

Lots of piss.

It's a book qbput a guy who can't go backwards named Robert Forward. It is by 3 authors: Alexander L'Hiboux, Never Sleeps, and The Owl.

Main character gets a clue (impossible for owls (because of tiny bird brains) )

He turns into an owl of course

A man falls in love with a sapient owl, who somehow returns his advances. His owl GF can't really stop hunting at night so he agrees to keep himself up at night so they can date. This has the consequence of poor work performance, putting his job in danger and making him seem weird to everyone around him. He must now juggle his owl-dating life and his human loved ones.

Hiboux is French for owl. So it's Alexander the Owl Never Sleeps. It's about an owl with insomnia. It's also written by Robert Forward, who I'm going to assuming is the classy author name of Bob Forward, writer of The Legend of Zelda cartoon and Beast Wars

An owl highschooler receives sweet morphin powers from Zordon, but now teenage life will be constantly interrupted by putty attacks, leading to sleep disruptions until Rita Repulsa can be stopped
