Thanks to NetGalley and Entangled Publishing for the opportunity to read and review Enigma by Tonya Kuper! Reid and Josie are undercover because they are being hunted by the Oculi headquarters. They want to reach the Hub, the Resistance, and find out who the mole is. They make it to the Hub and don’t know who they can trust, as they keep working on Josie’s training. The mystery of the mole is solved and the entire Hub is compromised. The mystery and suspense kept me riveted and Josie’s anxiety was definitely warranted. The author discusses anxiety after the story ends and gives hotline information for readers who deal with their own anxiety or know someone who does. 5 stars for this fantastic sci-fi story with realistic, lovable characters and unique abilities!
