Numbers Challenge

I have decided to take the numbers challenge. These books will double as some of my TBR challenge.

1. 1421 by Gavin Menzies
2. Die dritte Tür by Patrick O'Leary
3. 1st to die by James Patterson
4. Seven Ancient Wonders by Matthew Reilly
5. Eleven on Top by Janet Evanovich

The last one means I have to find book 10 that I had last week and can not lay hands on this week and read it.
