Evelyn Summers is imprisoned for a crime that was wiped from her memory. In order for Evelyn to be released, she--along with other "reformed" prisoners--must pass seven mental, physical, and virtual challenges known as the Freedom Trials. One mistake means execution and, with her history of being a snitch, her fellow inmates will do everything they can to get revenge. When new prisoner Alex Martinez arrives, armed with secrets about Evelyn's missing memories, she must make a choice.
