This book! Oh my gosh! So many people have recommended it to me. This book is about a crew of sapients, human and non-human, tunneling holes in space. They have to live with each other for long lengths of time. What does that do to a group? This crew becomes really close, except for, as you may guess, the one asshole in the group. I love the incredibly detailed and thoughtfully written aliens. I love that the ship’s crew, including the AI, are basically chosen family. It reminds me of Cedar McCloud’s writing in that the novel keeps subverting the dramatic directions I think it’s going to go. One friend described this book as a comfort read and I think he’s right. I can’t wait to read the rest of the series.
