I wish I could figure out why this book is starting to annoy me because on paper (lol) it’s a really fun story. It’s at least partially this particular reader—any characters from the UK are fine, but the rest are regrettably atrocious.
Partially also that I lost interest the “second” narrator pretty quickly. She starts out so interesting and then idk, it became a slog for me when the novelty wore off.

Why is this book somehow part of the CSEU (Clive Staples Expanded Universe)
