 The trilogy deals with the aftermath of the death of Wonder, Ashleigh's favorite racehorse, as well as Christina's decision to shift her focus from eventing to racing in order to become the jockey of Wonder's last colt, Wonder's Star.This has led to mixed criticism as some wanted Christina, whose preference for eventing was so clear that she often felt like an outsider, to stick with eventing.Others were pleased, but most agreed it was a too-sudden turnaround.
