@prasad - yeah, i read a lot of crichton...in fact i've read all of his books except maybe one or two
as for robin cook, you read a few of his books and it seems u've read them all...his books are way too repititive
my suggestion
Stephenie Meyers - Twilight, New Moon, Eclipse, <fourth part due in Aug 08>, <fifth part will be out later>
the above books are part of a series and are very gud. i'm currently reading new moon
