State of Wonder and Before I Go To Sleep

The best thrillers sometimes turn out to be the ones that aren't even billed as such. To be able, at the end of a book, gasp with surprise, is a rare pleasure. That gasp was the difference between Ann Patchett's State of Wonder and Before I Go To Sleep by SJ Watson.
The blurbs on Watson's book referred to it as "Memento on meth" and it was reminiscent of Memento. Christine wakes up every morning with no memory and has to quickly learn who to trust. A daily phone call from her doctor tells her where to find her journal, where she writes down what she pieces together (and what she also has to read every day) about her life. It is a fast paced if generally unbelievable book. It didn't take me long to figure out the real story, although in the end there were a lot of unanswered questions. Still, it was entertaining!
State of Wonder reminded me of Bel Canto-- many unrelated characters thrown together, forced to interact and with the outcome a surprise. Marina Singh is sent to the Amazon by the pharmaceutical company she works for to get an update from her med school mentor, Dr. Swenson, on the latter's research and to find out more about the mysterious death of her colleague. Marina becomes enthralled with the Amazon tribe she lives with, Dr. Swenson's research, and Dr. Swenson's "adopted" son Easter. The final Amazon scene is exciting as any Indiana Jones movie and my jaw dropped.
3 stars for the Watson book and 5 stars for the Patchett.
