The Catalyst is a dazzling, science-y, SFR adventure, full of kinetic excitement, that never retreats to formula. I could not put this book down. The beginning was a slow build on the science side, but never boring; I anticipated each new day of the DNA experiment. The middle and end were full of plot twists and menace. The romance was a compelling factor, but divided loyalties on behalf of the main characters influenced actions to an unexpected degree. The sensuousness is on the tame side, while the characters really are not.
Robin is a genius, and her demeanor starts out clinical and cold. Her gradual warming to her DNA experiment that is a "he" is engrossing. I have read hundreds of SFR books, and the progression of this "romance" was one of the most unusual that I have read. No quick leaps to lust or love. The romance is more a growing regard that begins to show shades of attraction. Remember, the very smart Robin is dealing with extra-terrestrial DNA, and she doesn't forget it for a minute.
I also have to say a few words about the author's settings. Mara can really put together a place and a scene through her words. This book runs the gamut from university science buildings to Robin's apartment to seedy bars and rural Illinois fields in winter. I could literally feel the cold she described and hear the rustling dead cornstalks. Plus, I have to do a shout-out to her inclusion of Mississippi river town Quincy, Illinois. I've been there, with its incredible historic mansions, and how she describes Robin's trek through the town was fascinating.
I was a little frustrated that the Amazon reviews were so few and so....spare...., but after reading the book, it really would ruin the suspense for future readers to reveal the slightest details regarding the direction of the plot and the results of the DNA experiment. Devi Mara keeps you guessing from chapter to chapter and the book goes on an extensive journey of emotion, plot and setting. The Catalyst interested me so much that I wanted to be challenged even more regarding the ethics dilemmas that cropped up at the beginning and then again at the end of the book. The conclusion really was audacious, and did not arrive at any simple victory or revelatory conclusion. The end was a glorious mess in the best possible of ways without being a cliffhanger. And since the title says "Book One," I much anticipate "Book Two."
