Island of the swans

The first part of this book was very engaging but then it just turned tedious suddenly; I only skimmed the last 150 pages and am quite sure that I missed nothing. This book was trying very hard to be historical fiction, I think it even had daydreams of being a biography, but was really just a romance novel set in the past. And badly set there. The author's need to cram in historical figures is just farcical; I didn't know whether to laugh or cry at the whole Robbie Burns episode.
I'm kind of sorry I wasted my time finishing it.
