No, Percy Jackson and the Lightning Thief was in the first series and Heroes of Olympus is the second series (Lost Hero, Son of Neptune, Mark of Athena) Hope this helps :)
there acually is no new series it is going to continue talking about Percy in the lost hero
Actually the 'Percy Jackson and the Olympians' series is over. The new series 'Heroes of Olympus' doesn't focus on Percy, there are only appearances and mentions of the previous characters.
The Kane Chronicles come first in terms of publication order. The series was released before the Heroes of Olympus series.
The Heroes of Olympus was released in book form on October 12th, 2010.
