The Rook by Daniel O’Malley
After hearing from several reasonably reliable sources, Myfanwy Thomas accepts the fact that she will soon awaken in a London park, surrounded by dead bodies, and with her memory gone. Knowing what's to come, she decides to leave instructions for her future blank-slate self in order to ensure her survival and to hopefully get the wheels started on figuring out who wants her dead. When the novel opens, Myfanwy is just waking up as predicated and quickly discovers she is a Rook, a high-level operative in a secret agency that protects the world from supernatural threats. From there, Myfanwy must uncover the truth about who is behind the attack that left her memory wiped, a threat that looks to become a full-blown mole hunt.
This was...quaint. Supernatural mystery cuteness. It reminded me heavily, in both character and world vibes, of the Artemis Fowl book series by Eoin Colfer. The thing is, those are spectacular fantasy novels that skirt the line between middle grade and young adult books, and as far as I could tell, this series, known as The Checquy Files, is not intended to read that young. But the playful nature and Nickelodeon-esque supernatural elements certainly lend a hand in that feel.
I think this is one of those series that, if this is the first time you encounter that level of dry wit and lighthearted whimsy in a supernatural mystery series, this'll feel loaded up with charm and freshness. And while I enjoyed myself and the story, it did feel a little long for what you get and lacked a certain level of uniqueness simply because I've encountered this before. I'm not positive I'll continue with the series, but the second book is on my TBR for the moment.
