I loved the premise of this book - that someone sharing Anne Frank's 'Secret Annex' could provide an alternative viewpoint of the time spent in hiding - but the execution itself was a little disappointing for me. Whereas the 'real' diary is packed full of trivial, but compelling information (meals the families ate, gifts given on birthdays, gossip from outside), 'Annexed' focuses mainly on the very insular thoughts of teenage Peter van Pels, separated from his girlfriend, feeling lonely and awkward among the strong female characters. The author seems reluctant to provide the same day-to-day minutiae that were so fascinating in the original (possibly to avoid repetition) but equally seems to be wary of moving too far from Anne's version of events (out of respect for historical fact?). The book thus seems to be 'caught between two stools'. The end (recounting time spent in the concentration camp and on the march) is more successful - possibly because there are no detailed records of Peter's life after the Annex (that I'm aware of), thus allowing a little more poetic licence. There is also a moving section describing the various fates of all the other Annex occupants. In short, a very original idea, but not nearly as arresting as the real thing.
