try anything by Jane Green, Marian Keyes, Lisa Jewell, as slightly more intellectual rom coms.
if you want to move away from this genre then try tany of the following as a stonking good read, but also make you think a little:
The Time Travellers Wife by Audrey Niffeneger (sp),
In Her Shoes by Jennifer Weiner
Crazy for You by Jennifer Crusie
The Memory Keeper's Daughter by Kim Edwards
anything by Jodi Picoult
The Island - Victoria Hislop
The Shadow of the Wind - Carlos Ruiz Zafon
The Book Thief - Markus Zusak
A Town like Alice - Neville Shute (Oldie but favourite of mine)
Kathy Reich also writes really good gripping books, and I always find that Jilly coopers book although a little raunchy are very well written
"The Nazi Officer's Wife" by Edith Hahn Beer and Susan Dworkin.
"Sky Burial", "The Good Women Of China", "China Witness" all by Xinran.
"The Knock At The Door" by Mary Ahnert Touryan.
"Titanic Survivor(?)" by Violet Jessop, I'm not sure of the book's name but I am sure of the author.
All non-fiction, I'm pandering to a female audience as I don't think "Sail Ho" or "The Cape Horn Breed" will interest a woman overly.
'Mist over Pendle' by Robert Neill - about the Lancashire witches. A historical novel.
'Great Meadow' by Dirk Bogarde. Autobiographical.
'The Persian Boy' by Mary Renault. Historical novel about Alexander the Great.
Mary Stewart's trilogy on Merlin - The Crystal Cave, The Hollow Hills, and The Last Enchantment.
