Loved this - excellent story, well written, and brilliant character development! Plus, a cheeky little twist in there, too! 
I was a bit unsure at first as im not a huge fan of switching between 1st and 3rd person, but here, this is done incredibly well - you get used to it very quickly!
The story is brilliant, so much packed in to 150 pages but not an overwhelming amount - and subtle reminders are throughout so you dont lose pace with whose who or what part of the story they are with!
Really enjoyed this and look forward to reading more by this author!
