Although I'd never read a YA book now
Why not? The fact that I'm 47 isn't going to stop me from reading these new books. I was in my 30s when the last Trek YA books were being published, and I read them, too. It's another way of looking at one of my favourite fictional universes. And it's not like it'll take a lot of time to get through them.
Now, if you'll excuse me, I'll go back to waiting for that cheap box set of The Darksmith Legacy (Doctor Who books for kids) to show up in my mailbox.
