Parker's writing seems to have disintegrated. Which is a shame because book 1 was actually quite fun. There's an inordinate amount of fascination with making quips about how cute either Luke, Robin and Oisin are. Not sure why, that needs to be said over and over again.
Either way, the story just isn't progressing in an enjoyable way for me.

Might give it a go in the future but for now:
