Caterpillar or Luchadores?

I might have become a biologist if we had the internet and so many pictures of colorfully bizarre animals when I was a kid.  Probably less lucrative than working in pharma but nature is pretty cool at a macroscopic level too.

Here is a humble caterpillar (Phyllodes imperialis) that evolved a little Mexican-professional-wrestling-mask on its back, so when it's threatened it scrunches up, protecting its head and revealing it's super-powered alter ego.

(The white stuff is apparently supposed to be teeth but they don't work for me.)

The Iron Druid

Kevin Hearne's Hounded and Hexed:

A druid who's something north of 2000 years old has pissed off enough Irish gods that he moves to Tempe, Arizona to get away from them.  Not that they can't get there at all, but there's not enough oak or ash or whatever it is they need to cross over easily.  Unfortunately one of them finds him through the internet and crazy high jinks ensue.

I read this book and immediately got the next one in the series and read that as well.  To be sure, "crazy high jinks" includes a lot of fantasy violence, but otherwise I think the book delivers exactly what my summary would imply.  Even less complexity or shades of grey than a typical Dresden Files book, but it and the sequel are pulpy fast paced entertaining fun.

Oh, and did I mention the conversations he has with his Irish wolfhound?
