Threshold (Boundary II) – Eric Flint & Ryk E. Spoor

Our friends from Boundary are back in a pretty direct sequel to the first book. The race is on to find more Bemmie bases. The Ares Project, despite having managed to get a foothold on Mars, is strapped for cash and resources. With some clever manoeuvring they manage to get both, and set off towards first Ceres, then Enceladus.

The first book was nicely crafted, with excellent character development. This second one feels much more forced, especially the first half. I really enjoyed going back and seeing what the gang was doing after the previous story ended, but was a bit disappointed at the lack of a strong story. This series will never be “heavy” but it needed a bit more than this effort. That being said, it harkens back to adventure science fiction from an earlier time, before all the dark and broody bits that are so in vogue nowadays. And so I still liked this book more than it perhaps deserves. The ending wasn’t quite a cliffhanger but certainly lacked resolution, leaving the door wide open for a sequel. Yes please.
