The Help is a great read. Here are some more ideas, with stars by the ones I really really loved:
Young adult novels (these can be terrific):
fantasy --
The Hunger Games trilogy
The His Dark Materials trilogy
The Mortal Instruments trilogy by Cassandra Clare
not fantasy--
*The Disreputable History of Frankie Landau Banks, by E. Lockhart
Going Too Far, Jennifer Echols
Literary fiction:
*Love Walked In, Marisa de los Santos
Garden Spells, S. Addison Allen
The Guernsey Literary and Potato Peel Pie Society, Annie Barrows
*The Forgotten Garden, Kate Morton
Non-fiction:
The Blind Side, Michael Lewis
Freakanomics, Steven Levitt
Romance:
Anything by Jennifer Crusie or Susan Elizabeth Phillips
Mystery:
the Sookie Stackhouse books
Elizabeth George's Inspector Lynley novels
