I finished the trilogy and I need a recommendation.

First I want to say that I didn’t have much expectation going into the series and that’s why I ended up loving it so much. When I first read the title I was like cool Caraval = Carnival. Obviously didn’t go in that direction, but it definitely ended in my top 3 favorite series I have ever read. (I’m a big fantasy reader so I just placed it in that category).

But here’s the thing…. It’s been weeks since I finished and the one thing that I can’t stop thinking about is Jacks. I want to know so much about he’s background and where he came from and he’s powers, etc but I also feel like he’s character was really well developed in the books.

I know there is another trilogy by the same author that kind of explores Jacks but can some tell me a little bit about the trilogy (I think it’s called once upon a broken heart) and if the story centers around him.
