Sold to me as an homage to the heinlein juveniles, I was dead keen to get into this. There are a lot of nods to RAH - especially names, but the style and milieu also fit into the groove (although there are differences).

Chapters 13 and 28 sang out to me, and the whole story is full of the exciting and drive you'd expect from something from Heinlein in his prime, with perhaps an older, somewhat modernised layer of late-teenhood to peer through. To sum, an exciting adventure.
