What I wish I had from my books - easy. Edie's Iskant - her ship. It's completely tricked out. I might hope for better food stores than she has, but that's about it. Of course, I'd just go zipping around space and get myself lost. It's a one and a half person ship, meaning it's designed for one but can support more in a pinch. I wouldn't be interested in the pinch part. This pandemic-enforced-togetherness thing has me all about the isolation and not-another-person-alive-within-miles vibe of Edie's boat.
A close second would be the medical that exists in this series. Medicine isn't generally painful in my world. It might not be able to cure everything, but it's pretty darned good. I'm saying this after having my first nerve block for migraines done, and let me just say yeowch. Those injections in the face got my attention in the worst way, so I could do with some painless medicine at this point.
What would you want from any of the books you've read?
