Cass is not having the best of time when it comes to secrets. It's all very well being involved in a top-secret society, designed to keep the secret of the most secretive secret ever, but those pesky people called adults are keeping things from her as well - namely, her very origins. Can Max-Ernest and she wade through their junk store base and find the box she was delivered in? Can they survive the mysterious clown school they end up visiting? And can they keep a mystical tuning fork from falling into the wrong hands?

The second book in the series is reviewed [[If You're Reading This, It's Too Late by Pseudonymous Bosch|here]]. For younger readers interested in adventures based on magical-seeming food science and posh cuisine, there is [[Madame Pamplemousse and Her Incredible Edibles by Rupert Kingfisher]]. For a circus beginning for a young man who ends up battling the baddies in outlandish arenas of the world, we recommend [[The Palace of Laughter by Jon Berkeley]].
