After several months of reading (hey, I've got a lot of hobbies...), I finally finished "The Time Patrol" by Poul Anderson.
It's a compilation of short stories that I got when I joined the Science Fiction Book Club.
The story chronicles the efforts of Time Patrol agent Manse Everard to restore timelines that have been damaged by evil time travellers.
Though it was graphic in a few spots, the majority of the stories were very well detailed, and an interesting read. I'd recommend it, especially if you like historical fiction as well as science fiction.
