I was worried at first that it was title Sam Reilly #1. I hoped there wasn’t a cliffhanger ending, and there wasn’t. (At least not overtly cliffhanger-y.) The story was taken to its conclusion, but there was one thing left open to pursuing in the next book (or two, maybe). The story itself kept me interested. I took the author at his word as far as the science and climbing information went. Bottom line, I liked it enough that I’d read more by this author.
