A Crown of Wishes by Roshani Chokshi

He was adopted by the King but the advisors don't recognize him as a prince.  They treat him as a puppet and won't give him anything to do or any responsibility.  He hates that so he decides he'll go on a quest to win a wish.  He needs a partner, though.

St. Martin's Press and Net Galley allowed me to read this book for review (thank you).  It will be published March 28th.

Wishes are tricky things.  You have to be careful how you ask and just what exactly you ask for.  As he and the imprisoned princess who would be Queen of her kingdom head out, they know what they want.  But as they go through the quest they learn that you have to ask for your heart's desire in a way that won't come back to bite you.

This a world of fantasy with lots of challenges, a changing landscape, and a whole lot of danger from all sides.  The two stick together and work on making a successful mission by winning the wishes but it's not easy.  Others are just as desperate to get them and the other contestants are deadly.  Even the ones there and not participating in the quest are dangerous.

Then they find out only one person gets to return to their world.  They both want to go back.  They both also want their wishes.  

The story is exciting, very busy, and there are lots of other side characters that draw your attention.  I read this story in one day and I loved how it turned out.  There were a few misunderstandings but it ends on a happy note.  I really enjoyed this read!  It's an especially good read.
