I recently finished the fourth "Outlander" novel by Diana Gabaldon, Drums of Autumn. I really enjoyed it.
My Goodreads review:
Diana Gabaldon truly has a gift for keeping characters multidimensional and interesting over many, many novels. I thought this fourth take on Claire and Jamie would be boring - not so. Their lives have so many twists and turns….. This turn, their story in America, is so fascinating to read about. And I don't even enjoy American history!
Now I'm curious about the fifth novel - and that's a sign of excellent writing.
