This is the extraordinary love story of Clare and Henry who met when Clare was six and Henry was thirty-six, and were married when Clare was twenty-two and Henry was thirty. Impossible but true, because Henry suffers from a rare condition where his genetic clock periodically resets and he finds himself pulled suddenly into his past or future. In the face of this force they can neither prevent nor control Henry and Clare's struggle to lead normal lives is both intensely moving and entirely unforgettable.
Whilst I generally tend to enjoy most books I read (with the occasional exception) this one certainly stands in a class of its own. I would love to ask the author how she came up with this concept..... and how on earth she kept track of all the comings and goings!
Yes, it can take a bit of keeping up with as to "when" Henry is, and also as to how something that happens at one point in time affects how his and Clare's story unfolds, but it is so worth the effort to do so. It's the most unusual love story I've ever read and has to be one of the most fascinating concepts ever. Be warned though: have a tissue ready when the story nears its end.
