I'm doing my TBR Orphan update a bit early, but I'm fairly sure I won't be reading any extra orphaned books the last few days of this month.
I read one Orphan in May:
Wicked After Midnight by Delilah s. Dawson
It's been on my shelves since December last year, because I had to read Wicked as She Wants first before I could pick this one up.
How did your challenges go?
