Leap of Faith is now number 5 in the ranking of books with a Camelot theme. It's even beating most of the Merlin TV spin-ff books. It's even number 14 with the tag "Children Fantasy Adventure".!
I'm not sure how accurate or representative the rankings are, but Tertia and Unita and the whole Temporal Detective Agency is thrilled to bits. They also added that of course they were beating the Merlin books, because they have the real one and besides she's honeymooning with Arthur at the moment!
Can't argue with that!
