Once upon a broken heart has a sequel coming out this year I believe if not next (it’s a duology)Didn’t go for Six of Crows in the end- have stayed the house in the cerulean sea instead as heard very good things!! Also downloaded 2 99p purchases onto my kindle today- the Taylor Jenkins Reid one and Once Upon a broken heart as I’m getting into more fantasy books now
Apparently it helps if you’ve read Caraval as theirs characters and some back story from that book to give some context but it’s not a pre requisite.
I have them but haven’t started either yet, so I’ll be interested to hear your thoughts when you finally do, happy reading
