I honestly can't remember if I spotted Gen's identity or not in the first book. I inhaled these books all at once some years ago but haven't ever been back to them - your reread is making me think I might like to revisit them.

really, if you wouldn't get down on your knees and swear to die for this person, is it even worth calling it love?
Truer words were never spoken! (You can tell I grew up on Sutcliff, can't you...)
