If you're going to put years, you have to put other stuff into account. In TRP, Sadie was listening to 19, and it came out January 2008. In SoN, Thanatos used an iPad, which came out April 2010. In TTC, Chiron said that December 21, the winter solstice, was on Friday. And in SoS, Carter said TRP happened two winters ago.

So, using these facts, it's like this:

PJO/HoO

TLT-Summer 2006

SoM-Summer 2007

TTC-Winter 2007

BotL-Summer 2008

TLO-Winter 2009

Son-Summer 2010

MoA-Summer 2010

KC

TRP-Winter 2008

ToF-Spring 2009

TSS-Fall 2009

And finally,

SoS-???? 2010
