This is the third in the Molly Moon series and also - due to some confusion about titles, the first I read - or rather listened to since I go the audio book read very charmingly by Clare Higgins (who you may remember as Ma Costa in The Golden Compass movie). I was not very impressed with the story, unfortunately. The plot is that Molly Moon is kidnapped several times at different stages of her timeline, by a villainous Indian whose purpose was never clear to me, although I did DNF this, so I may well have missed it.
The Indian employed a lackey who was the one who actually kidnapped Molly. The lackey wanted to get back to the fountain of time or whatever it was, which he thought would restore his youth and looks (time travel apparently turns people into lizards, if they overdo it). The problem was that the entire story was one long repetitive slew of time jumps, which was interesting at first, because it was quite engagingly described, and one example of hypnotism was really quite beautifully done, but after the story kept repeating endless time jumps, and with Molly's dog being kidnapped to forced Molly's compliance, and then she getting it back and then it begin kidnapped again, it was tedious, to say nothing of confusing. I may have missed this, too, but I never did understand why they needed Molly.
On top of this, the story sounded faintly racist to me, as the Indian bad guy was given this absurd affliction of spoonerism, which rapidly became annoying to me. Obviously the story isn't aimed at me, it's aimed at middle-grade readers, so they may have a different take on it to what I did, but I can't recommend this one.
