Jason is living a completely pedestrian life as a prof at a second-rate Chicago uni with a hottie wife and artistic teenage son. Sure, he's got regrets - who doesn't? - and wonders wistfully about all the what ifs. What if he'd stuck with his physics research instead of getting hitched and taking care of a son in the NICU? What if his super attractive wife had elected to remain single and devoted to her gifted artistic vision? Well, luckily for Jason he gets to FIND OUT. Because somewhere else in the multiverse, there IS a version of Jason who made a physics breakthrough and created the perfect Schrodinger's box. Combine that with a bit of drugs to help the human mind comprehend the infinite realities of space/time, and you have a nifty little traveling device that whisks Jason right over into a version of his life that he's completely unfamiliar with. As you might expect, getting "back" home is less straightforward than Jason had hoped. The emphasis here is on the cerebral aspects of alternate realities, not on character development. That's a missed opportunity here, because I think had the wife and kid been more fleshed out I would have been way more invested in Jason as a character himself. A Martian-style exploration of some complicated physics facts fused with Dan Brown-style mad pacing makes for a quick read that will be a fascinating talking point at your next cocktail party.
