1) Sabriel by Garth Nix
Nix creates such a rich, vibrant world in his trilogy. As the first in the series, the land the the mythos is revealed in Sabriel in such a way that you feel you already know it all. This book can stand alone. There is no cliff hanger (unlike book 2). Between the covers you get a strong heroine, incredible magic, a hero, battles, intrigue, and so much more.
2) Moon Called by Patricia Briggs
This is, hands down, my favorite Urban Fantasy series of all time. I love it. How could I survive on a desert island without Mercy Thompson? Mercy is a no-nonsense kind of gal. She does not need to accomplish great heroic deeds, yet she is not a victim. She is your average woman in a world that is far from ordinary. A skin walker, she was raised among the werewolf community. Now she owns her an auto body shop and tries to keep a low profile. That is kind of hard to do when your neighbor is the head of the local werewolf pack, one of your customers in a vampire, and a newly turned were shows up on your doorstep with trouble following in his wake.
3) Mr. Perfect by Linda Howard
Sam Donovan. Need I say more?
4) Over the Edge by Suzanne Brockmann
The Troubleshooter series has provided me with hours of Alpha male entertainment. I could not leave for the island without at least one of them in tow. I chose Over the Edge because of Stan Wolchonok. He is strong, quiet, steady, Alpha, passionate, intense, and desperately love Terri. He is the quintessential average to slightly less than good looking guy made hot by the way he acts and feels. Stan is the kind of man you want in real life. He would lay down his life for Terri, but he does not try to hold her back in an effort to keep her safe. Ms. Brockmann imbued this character with such quiet intensity. I want a Stan for my own.
5) Harry Potter and The Prisoner of Azkaban by that disgustingly rich woman
Hey! You said you wanted a variety of genres. This is my favorite installment of the series. You get Lupin! Sirius! The Marauders Map! You know, we may want a break from romance once in a blue moon. Blasphemy, I know.
6) The Bride and the Beast by Teresa Medeiros
I had to throw in a historical. I was tempted to add The Raven Prince since I loved it so much, but we already have one of Ms. Hoyt's other novels on the island. I don't know what it is about this book that I love so much. I have read it more often than most books on my shelf. Mr. Perfect may be the only other title I have read as often. The theme of redemption, love overcoming all... ::sigh::
So yeah, that's my six. I hope you like them!
