If you loved 'The Last of August' for its blend of mystery, wit, and complex character dynamics, you're in luck—there are plenty of books that hit those same notes. One that immediately comes to mind is 'A Study in Charlotte' by Brittany Cavallaro, which is actually the first book in the same series as 'The Last of August.' It’s got that same sharp, modern take on Sherlock Holmes-inspired teens, with a dash of romance and a lot of clever plotting. Another great pick is 'The Naturals' by Jennifer Lynn Barnes, which follows a group of gifted teens solving cold cases. The banter and psychological depth reminded me a lot of the way 'The Last of August' plays with relationships and trust.
For something with a darker, more atmospheric vibe, 'Truly Devious' by Maureen Johnson is a fantastic option. It’s set in a boarding school for gifted students, and the mystery unfolds in a way that keeps you guessing until the very end. If you’re into the art heist aspect of 'The Last of August,' 'Heist Society' by Ally Carter might be up your alley—it’s lighter in tone but still packs a punch with its clever schemes and globetrotting adventures. Personally, I’ve reread all of these at least twice, and they never lose their charm.
