This is a hard novella to rate - As my first read by Bloom, I enjoyed her style and it was well written, however as a novella in its own right, it left me with more questions than answers, which I’m sure was the authors intention, it just didn’t feel … satisfying to me. Prequels are there to whet the appetite, to sow the seeds of the series to come, and it did do that, but many that I’ve read are also reasonably complete stories that leave you with that feeling of satisfaction whilst still having the eagerness to learn more about the characters and what happens to them next. Lost left me with so many unanswered questions it was hard to relate to the characters or form any emotional attachment when so much was hidden from us. I have a pretty good idea of what happened to both Rebecca and Josh from the breadcrumbs provided and at some stage I will continue with their journey, but there was too much unanswered for me to “need” to buy the next book and devour it now. 3.75* from me, with the expectation of a great rating once I delve into a full length novel by Bloom and have a chance to form a attachment to the characters.
