Sometime around 2005 to 2007 I read a book that told the story of an alternate history Earth that took place around World War 2. This book was part of a series but not the first or last book (I only read this one). The premise was that aliens (a race of lizard people) were invading Earth.
Points I remember:
- The aliens had sent a probe to Earth during the middle ages. They decided to send an invasion fleet because at the time humans were at a very low level of technology. The aliens were surprised that humans had advanced so much in the intervening centuries because all other races they had encountered (including their own) moved at a very slow pace.
- The United States nuked Chicago to try and drive the aliens back.
- The aliens had taken custody of a new born from south-east Asia in an attempt to learn more about humans.
I'd really like to find out who wrote the series or what the title(s) are so that I can read all of them.
