I liked it.
It actually made me really sad at times. How Jack was ostracised and Rion's isolation was kind of heart breaking. The lapsed Catholic in me also picked up up on, what felt like, a lot religious undertones but I might just be reading too much into it. Rion's life in particular felt very religious orderish and the people being afraid of the 'giant in the sky'? But again I might be just reading too much into it and 'Jack and Beanstalk' always felt a bit that way anyway!!
I thought that this was going to be a light funny read and in parts it was but it also kind of struck a cord and was sad and really harsh at times. It surprised me but I'm very happy I read and I enjoyed it immensely.
