What to do?

Coffee and fantasy, two of my favourite things...

We're a week into the new year, and things are going nicely over here! We're having fun, getting out despite the cold (in our part of the world, it's been around -20*c for the past week!) and just generally enjoying life.

I've run into an odd problem though. I've set myself up with the reading challenges I posted about just before the end of the year, and I'm stuck on a book that's not part of either of them. It's by an awesome author, Marissa Meyer, who also did the Lunar Chronicles series, which I loved. Renegades (link to Goodreads) seemed like it would be amazing based on a sample I got to read a while back, but I'm finding out that I'm not even to that part of the book yet, and I'm already on page 150 or so. There's so many characters, that use double names (real name versus hero/villain name) so there's another problem, trying to remember who's who!

I've been struggling, trying to read it for about three WEEKS now. Which is crazy. I used to be able to read a book a day before I became sick, but I never slowed down this badly.

I'm tempted to put it down, and try again later, so I can get a move on with my challenges.

I don't want to give up on it though. What do I do?
