Corrected entry: When Holly and Artemis are atop the temple of Artemis in the 11 Wonders Theme Park, it says "Holly pulled out the dead cells, tossing them aside", yet on the very next page, it says "Holly drew back her arm, sending the spent power cells skidding across the roof." How could she throw them twice?

Correction: It's likely that when she "tossed them aside", they merely landed on the ground next to her. Later, she would then have the opportunity to throw them again.
