Always a fan of L'Engle's works, but this one is a bit more juvenile than many of the others... Having read this immediately after finishing Meet the Austins I can say that L'Engle was able to keep Vicky's 'voice' in tact, while at the same time maturing a bit - it sounded like the same character, but more like a 14 year old than a 12 year old. A subtle but important difference, one that, to me, highlights how talented L'Engle was. I liked the teenage-angstyness of it, and even though Vicky is suddenly attracting boys it is not superficial, but because she is herself and not willing to bend that. The only thing I found completely unrealistic was the fact that they managed to keep running into Zach everywhere they turned - the US is a huge place, with tons of campgrounds, and being on a different timetable and with different destinations in mind it just seems unlikely that they'd see each other as often as they did.
