I finished The Laat Lifeboat by Hazel Gaynor. It's a fictionalized retelling about a British ship carrying evacuated children to Canada that was hit by a torpedo from a Nazi U boat. One lifeboat was not rescued for many days. I usually don't enjoy fictionalized retellings like this, but I actually really enjoyed this one. The author took the facts surrounding the lifeboat and populated it with entirely fictional characters, giving her more leeway to properly plot the story out and give depth without having to make up things about real people.
I just started Grendel by John Gardner, a retelling of Beowulf from the monster's point of view. Too early to say how I feel.
