I don’t have too much to say about this one. It’s a wildly entertaining underwater story by Jim Krieg with a rescue, a safe-cracking job, and the menacing Mechanic back with his second massively powerful machine. Our son loved it, and I laughed out loud a few times.
It’s set in a place called Bay City, where Lady Penelope’s grandfather once had a penthouse office. He was apparently in the architecture business, and specialized in designing prisons. Bay City was lost a couple of decades before this series began, when the oceans rose and sank everything on the coast of whatever unnamed nation this is. Calling it Miami might have been a bit on the nose.
