Reading Away The Night

So for a Secret Santa I'm participating in, I received two sets of books: The Alexander Trilogy and The Children's War, both historical fiction works that I thoroughly enjoyed. I had previously described a book which was probably the first book I read for leisure in about six years to occupy my time during some flights. However, I read these books and an age-old problem kind of reared it ugly head at me.

It kind of makes it hard to then get enough sleep for work the next day, and then I'll go through long periods without reading a book for leisure. If only I had more self-control over books...
