I haven't read as much HF as I thought this year and looking back at my reads there's only one book I gave 5* to - Kate Lord Brown's The Perfume Garden that made me research about the Spanish Civil War and haunted me for weeks afterwards. This was the book I mentioned last year in my "eagerly anticipating" post so we can say my expectations were fulfilled.
But there are a few more books that also deserve a mention because I found them very enjoyable:
Oleanna by Julie K. Rose
Hungry Hill by Daphne du Maurier
Defend and Betray by Anne Perry
