Have you read Michael de Larrabeiti's Borrible Trilogy?

Yes! I bought them in battered paperback from used book stores because I'd liked his Provençal Tales, which are completely different. I'm glad to hear they're back in print; they're some of the grungiest YA I've ever read.

This Simian World sounds fantastic, a bit Olaf Stapledonish. I would love to hear more about it.

I'll see what I can do. I'm pretty tired.
