Not a bad book. The author definitely has character dialog, interaction, and behavior down. The plot was pretty decent, though it didn't really get interesting until about halfway through.
My reason for the three stars is mostly because the book reads like a cheap romance when describing characters. Example: "He yanked once more but couldn't seem to make any more progress. Hunkering down, grunting, he jerked with all his strength, the effort burning in his biceps as he strained to free the trap," and the author is way too fond of descriptive words with an -ly suffix, to the point where it tends to jerk you right out of your reading revelry to realize you are, in fact, reading. Example: "Grins blossomed, and clumsily suggestive offers of help tumbled out, echoing off dreamily reflective walls." The author even used the most cringy of -ly descriptors - "funnily." So yeah, not the best read in the world, but definitely not the worst and well worth reading if you really love the CSI shows.
