I just read this little quickie (I wasn't even aware it existed and then immediately went and bought it) and thoroughly enjoyed it. I adored On The Island, and reading some more of T.J and Anna's relationship, plus the mystery of the bones on the island was absolutely fab. Nothing was overdone. It made me happy and did everything a novella is supposed to do. I could probably have done with a little more character development from Calia and maybe some clearer writing on the whole 'incident'. I think that should be clear enough.
Overall, pretty great.
