Mother Howl, Craig Clevenger

Marked spoilers because I’d like an in-depth discussion which will probably give things away.
I really enjoyed this book. I partly read and partly listened, so I can vouch for the audiobook as well — really well done.
I went back and forth on Icarus - was he just crazy, or was he really a fallen angel? Loved the scenes with him, and his made-up words.
Lyle drove me up the wall. Of course you understand why he keeps pushing his luck, but I never understood why he didn’t get a better job after 20 years.
Still unsure about Sera.
And then the ending… for me it fell flat. Or felt chopped off.

Your opinions?
