Hmmmm. That's a toughy. Probably either Unwind or Full Tilt by Neal Shusterman, or the Bartimaeus Trilogy by Jonathan Stroud. I love them. One is greatly funny, and the others are filled with mischief, mazement, power, and great suspense. Both of course have amazing description that I've seen no where else. =D
I've got a special place in my heart for so many books it's hard to choose. It's also difficult to be objective because I tend to feel particularly attached to a book while I'm reading (or in the case of a favorite, re-reading) it. I will, however, say that of everything I've read the best all-around book(s) have been by Patricia Briggs. At this point I haven't read everything she's written, but her Mercy Thompson series is amazing. I wouldn't recommend them for anyone not yet into their mid to late teens (as there is some mature content), but they really are worth trying.
I dont have one favourite book really. However I do reread a number of books, Thomas the tank engine, Dr Dolittle, Winnie the Pooh. Yes I know they are childrens books and I am an adult but does it really matter. If you enjoy them.
I don't know, I read a lot, I literally devour one good book after another. However, I can name a few memorable ones: Harry Potter, a few books from the Redwall Series such as Mattimeo, Redwall, Mossflower, Martin the Warrior, or a few books from the Royal Diaries. I usually read books people have forgotten about, I tend to ignore the bestselling ones like Twilight, Hunger Games, Vampire Diaries all except for Harry Potter.
Very tough, seeing that almost every book I read I absolutly love. Probably Lament and Shiver by Maggie Stiefvater,Beautiful Creatures by Kami Garcia and Margret Stohl,Thirst by Christopher Pike, Strange Angels by Lili St. Crow, Vampire Academy by Richelle Mead, too many others to count.
