Really 3.5 stars.
This wasn't the best Mary Stewart I've ever read but a slow bland start was more than made up for by an exciting (if slightly implausible) finish. As always the scenery was wonderful and as with her other romantic suspense I've read, it had a real 1950s/60s filmic quality about it. Fluffy but fun, with Shakespearean references thrown in.
And a special thanks to the 'book fairy' who sent me my copy as a present. It was much appreciated.
Buddy read with Kim and lots of others over at the Mary Stewart group :-).
