Thanks, Deb - I'm touched you want to read me! Yes, there's a few options - there's half a dozen or so in the Castlemere series, about the same with Brodie Farrell.
I suggest you buy one - whisper it, but you could get it cheap off Amazon, in case you don't like it! - and take it from there. In either case - "A Bleeding of Innocents" was the first Castlemere book, "Echoes of Lies" the first Brodie Farrell - if you enjoy the first book you'll probably enjoy the rest: I think they got better as they went along.
There are paperback editions for a lot of the books but not all; and mass-market (cheapie) editions from Worldwide Mysteries for some of them. And one of them you could read in Japanese, if the notion took you!
If you find one, let us know what you think of it. I'm a big girl now: I can cope with criticism! But thanks again for the interest.
