I love our new narrator. I love the mystery plot of this one. I love the slow romance.

I also want to praise the technobabble in this novel. Yes, it's taking about 5-D wormholes. But (and I'm saying this as an engineer), the engineers talk like engineers, and the words they say make sense and convey the concepts clearly. Honestly, the technobabble in this series is the best I've ever encountered. Not too much or too technical for someone who doesn't care. But also accurate and enlightening enough to explain it to someone who does care, like me. Obviously some research and actual science went into it.
