THE DOWNSIDE by Mike Cooper is advertised as being a "fast moving thriller....hurtling along at breakneck speed". This reader did not experience the thrill AT ALL. It my opinion, I felt it the pace is laborious, slowed down by technical jargon ( tunnel boring machines, excavator dimensions and weight, tapping into high voltage power lines, etc). All the technical details muddle the action of the storyline. The transitions from one chapter are choppy, jumping from one scenario to another, which disrupts the flow of the plot and is confusing. The characters are flat and one dimensional; I did not relate to or embrace them, and did not care about them or their fate. Therefore, the characters nor the action push the plot along, and instead of building to dazzling excitement, I was dazed with frustration and confusion. Another major flaw in the ( lack of) character development is the fact there is no MOTIVE behind their actions to commit another heist, funded by the same person who betrayed them before, which caused their arrest and imprisonment. I mean, how stupid is that? These are intelligent people, supposedly, yet they jump back in the fray after just being released from prison? No mention was made of parole checks? All the red flags are presented as a warning they are being duped and betrayed again...Whaaat? As has been quoted by Jodi Picoult, " When you have been burned by fire once, you don't jump into the flames again." Exactly. But these people do just that, defying logic and common sense, which makes this caper silly, implausible, and a waste of time.
