Title: The bar code tattoo
Author: Suzanne Weyn
Publisher: Scholastic Inc.
Series or stand-alone: #1
Outside, rain drummed against the window.
Kayla Reed is about to turn 17, the age when she can get her barcode tattoo. However, when a traumatic thing happens in her life, it triggers an expanding suspicion of the tattoo or "too", in this book. Along with a small group of other teens opposed to the tattoo, they work together to find out what's up with the barcode and Global-1, a company which seeks to control the world.
This was quite scary in a 1984 Orwellian way but a very interesting concept. I've put #2 on my TBR list.
