Our Infinite and Inevitable Ends by A.D. Sui, 312 pages.
Dr. Cassandra Barlowe is doing thankless, underfunded research on the Great Pacific Garbage Patch in a world that is rapidly spiraling towards climate apocalypse. Partially because she cares about plastic-eating fungi, and partially to get as far away as possible from Dr. Yana Gulsvig, the brilliant scientist of an ex she had an intense lifetime relationship with. Part of the reason her funding is so non-existent is because of Yana's own research on deleria, a drug that lets people look into other timelines to deal with their grief or search other timelines for the perfect solutions to Earth's problems. When Yana calls Cas right before the center of deleria research explodes with her inside, she is called back to Canada for a domestic terrorism investigation, and once she's there her own grief for Yana pulls her into a desperate, drug-fueled, investigation into why she died.
This book has one of the coolest concepts I've heard recently. The deleria is a great idea, and the framing device sounds great for a high-tension thriller. Unfortunately, the execution left something to be desired. I think this book needed at least a couple more of rounds of edits. There were a whole lot of details that didn't really make any sense (getting internationally arrested as a terrorist after a 1-minute phone call with someone you haven't spoken to in years, threatening to frame someone for a crime in a world where everyone is wearing recording devices in their eyes at all times, etc.) that added up to something that didn't feel very cohesive. Which makes this the most disappointing kind of book, because I can clearly see the bones of a great book underneath, but it is not what I'm reading.
