I figured this out.
Double Cross is erotic SF. There is a market for erotic SF!
People of the Earth may or may not be YA Fantasy (I’m concerned what Rinai and Matti go through might be too much, making it Fantasy about YA’s rather than YA Fantasy, the way Ender’s Game was originally marketed to adults), but it’s certainly my best novel yet. Other than some backstory that needs adding in midway through and the obligatory removal of ‘was’ (my secret vice while writing first drafts), it’s about ready to send to my critters.
