Esperance hooked me from page one and didn’t let go. I mean, how could it? It opens with an impossible murder - a father and son drown in seawater inside their 20th-floor Chicago apartment (with no water tank around, floors dry, and nail scratches on the ceiling). A dead barracuda is just lying there next to them. For me, that’s the kind of opening that demands attention, and trust me, Oyebanji knows exactly how to keep it. 

All of this somehow ties to a woman in Bristol who dresses and speaks like she walked out of the 1930s Nigeria, has and builds tech that shouldn’t exist, and is on a very specific historical scavenger hunt. Yeah, I’m in.

The pacing is perfect - the short chapters told from two points of view (Detective Ethan Krol and Abi) fly by quickly thanks to the right mix of action, mystery, and those oh-crap moments where everything shifts. The sci-fi elements are there, but Oyebanji doesn’t over-explain them, which somehow makes them even cooler. I found the twists top-tier, but your mileage may vary. Anyway, just when I thought I had things figured out, nope. With that said, it’s possible some readers won’t be crazy about police procedural elements, but since I love them, I had no issues here.

I also loved the dynamic between Hollie and Abi. Hollie is basically most of us. Abidemi, on the other hand, is an enigma - charismatic, dangerous, and inhumanly brilliant. Their relationship had the odd but interesting energy, and I loved how their interactions went from trust and suspicion and back.

Even the antagonist had motivations that actually made sense. There’s logic to their actions, even if their methods are, let’s say, a lot.

By the time I hit the final act, I was all in. The twists come fast, the revelations hit hard, and the ending is equally satisfying and unsettling. I feel it’ll stick with me. If you’re into Blake Crouch-style thrillers, Neal Stephenson-esque tech mysteries, or just a smart, fast-paced story that refuses to be predictable, Esperance is absolutely worth your time.
