I agonised over this a bit and would say 3.5 stars verging on 4.
This to be honest is not the sort of book that I would normally pick up but I had read a lot of good things and saw it on sale.
The prose was really lovely at times, the circus itself was wonderfully imagined.
I didn't really warm to any of the characters to be honest. The contest didn't provide any tension. The central romance didn't feel real to me either and in fact there wasn't, in a lot of ways, much of a tale told.
