This Sequel Is Even Better than the First Book
This is the sequel to "Last Day on Mars" and is part of the continuing series "Chronicle of the Dark Star. I don't know what's planned, but it feels like it will take at least two or three more books to wrap up the whole series. You could start the series with this book, but that would be an unnecessary challenge. If you are patient and are willing to piece things together you could probably figure out how this all starts. But, it would be a lot easier and a lot more rewarding to just start with "Last Day on Mars", which is a fine book on its own, anyway.
But, this sequel is way better. The first book, in retrospect, seems fairly standard. Earth is already burned up, everyone's holed up on Mars, and the big deal is that everyone is escaping Mars before the Sun goes nova. So, it starts as a Mars colony tale, then a humanity in space/colonization tale. Our two heroes, Liam and Phoebe, get left behind and they and the AI JEFF have to catch up with the fleeing fleet. In addition to all sorts of space acrobatics, there are lots of hints about sabotage, other dangerous alien civilizations, hidden conspiracies, and the like to keep the pot boiling.
But things really speed up and take off in this book two. I'm not a fan of time travel and not really thrilled by parallel universe stuff, but that's the heart of this book and by gosh the author makes it work. Bottom line, Liam and Phoebe are still trying to fight off or avoid bad guys, they're still trying to catch up with the Earth fleet, and they're still trying to figure out who those guys are who are randomly blowing up suns, (like our sun). (Is it something personal or just the side effect of something else?)
Anyway, MILD SPOILERS, it turns out that with the help of a gizmo Liam found on Mars Liam can travel back and forth through time and can switch from one time line to other parallel time/event lines. The secret to this being readable is - 1) there's not too much of it, 2) we don't get bogged down in paradox baloney, 3) a wry and deadpan funny chronologist keeps joining Liam to explain what is/did/was/will/will have/ has been happening. Liam asks the chronologist exactly the questions the reader would ask, and the chronologist gives straight answers that sound both plausible and scientifically sound, in a quantum space/time sort of way. Amazingly, this makes the time travel and multiverse stuff both entertaining and very effective for plotting and action purposes.
So, I admit I expected this to be mostly space action, asteroid dodging, friendship bonding, space opera, (which is fine). It turned out to be more engaging, more sophisticated, more rewarding, better crafted, more gripping, and more satisfying than I could ever have hoped for. There are even interesting twists and turns in the Liam/Phoebe story that kept that angle fresh and intriguing. So, a very nice find and one of the few sequels that outdoes its predecessor.
