Is Irrel suddenly shipping slash? Nah.
Meet Alek and Deryn from the Leviathan book series by Scott Westerfeld
, biggest ship tease ever. Alek is a prince on the run and Deryn is a girl dressing up as a boy to be a soldier. Problem is: Alec has no idea XD
If you're looking a book rec, read this! It has it all: Mecha, steampunk, alternate history (WWI~), fabricated animals, awesome female characters, and of course... our-love-could-never-be ship, my favorite kind!
*waits patiently for third book*
Oh, yeah, did I mention they're sitting on a flying whale?
ETA: Fanart heavily based on the book illustrations, btw. For example!
