When I read that first line, "I didn't want to resurrect my dead sister because I loved her," I knew immediately that this book was going to be a wild ride. I already love the idea of a main character who's diving to explore ancient underwater cities in hopes that she can find something to trade and work towards reviving her sister, and I also am really intrigued into how palindromes are going to come into play later because I've always found them to be fun and they're fun to point out when you spot them.
