Suggestions requested - I like mysteries and books by Alice Hoffman, Elizabeth Berg and Anne Tyler. ~TIA~
The author Janet Evanovich writes mysteries and is very funny. The main character is Stephanie Plum and she is a bounty hunter. I've one friend who literally laughs outloud when she reads her books. There are fourteen in the series so far, she's been adding one about each June for the last few years, not sure how often the years prior. There's a couple in betweeners too, sort of little spin offs with the characters, but inbetween the main books, I think they called them 'a between-the-numbers novel.' Her first of the series is One for the Money, then Two for the Dough and Three to get Deadly. I work at a small town library and that is one of our most popular series for sure! Have recommended it often and haven't yet have anyone not like them!
The twilight series as already mentioned is also very, very popular with young adults and adults as well. My daughter loved it and is very excited for the movie to come out in Dec.
If you like christian or family novels at all, there are a couple series by Karen Kingsbury(and Gary Smalley). They follow the Baxter family about a doctor and his wife who have five adult children, and who have a strong faith that they try to live by. It is really good and inspiring, while being in the real world we live in and definitely not preachy at all. There are five books in the first series, each one follows one of the children for it's main focus, but also including the whole family. It begins with the Redemption series(redemption, remember, return, rejoice, reunion), and the second is called the Firstborn series, and the third is the Sunset series. Highly recommend these often, too, and everyone seems to love them. As I said, not preachy at all, but still nice and clean and interesting to read as they follow the family for generations, as it goes into children of the original doctor Baxter and then into their grandchildren in the second series.
Sue Grafton is a mystery writer with the alphabet series such as "A" is for Alibi, and Mary Higgins Clark has a lot of mysteries and is pretty popular.
Debbie Macomber is also very popular, as well as Jennifer Chiavarini with her popular quilting series, though not mysteries.
Jodi Picoult is also very popular, also mentioned earlier, and those books were quite popular. Her latest is Change of Heart and is really good, and sort of a mystery as you try to figure how things will go, etc. Very thought provoking, as her others are also!
Good luck finding something fun to read on your trip and have a great time!
