Holly's Inbox by Holly Denham.
I was a bit confuzzled at first because this is a fiction book, yet the author's name is the same as the main character's... But after a little research on the Internet, and if I believe what I read, then the author's name is a pen name for someone who wishes to remain anonymous.
Whew. Now that I've gotten that out of the way. Holly's Inbox is an enormous work of women's fiction. It's 665 pages long, but don't let that scare you as I think most of the pages were taken up by formatting. See, Holly's Inbox is all in email format. We meet Holly, her crazy friends, her coworkers, her parents, her hilarious grandmother all through email communications.
Have to admit it took me a bit to get into this book. It's a little slow going at first, but quickly makes up for it as layers are revealed. It's set in the UK and has a bit of that Sophie Kinsella / Bridget Jones flavor.
If you're looking for a fun chick-lit book for those long summer days, you might want to give this one a try. For more info, check out the book's website: www.hollysinbox.com.
