ECHOLOCATION by Myfanwy Collins has me thinking about fission. At first I thought of the collapsing of the universe, but, without giving away too many spoilers, this is more about the collision of distinct, related women and the resulting release of energy. There is destruction and creation in the series of events. Examples of gain from loss begin in the opening pages when Geneva (the main character and the most morally compelling) loses her arm but gains freedom.
I think the greatest momentum in the novel is created by the consistent PRESENCE of the PAST. This particular aspect of the novel reminds me of Alice Munro, whose characters seem like mental time travelers, moving between now and then. Collins juggles Renee, Cheri, and Geneva and I'm curious what she'd be able to do with just one character put under the microscope of her sentences.
The closing ~30 pages is quite interesting as it reveals more memories than I expected from the climax of the novel, cementing Geneva as the emotional core of the novel, the potentially tragic figure, and the one who still lingers after I've shut the book.
