Q-in-law is a really good book, I also like the audiobook of that one a lot. A shame that Q-continuum trilogy never got audiobook versions, even if they would have been abridged versions I would not have minded if John de Lancie would have been the voicing it.
That would've been cool indeed.
As a consolation prize, I did
get John de Lancie to autograph a copy of the omnibus edition at Shore Leave a few years back.
And I believe the Q books are still my best-selling Trek books, for which I give full credit to the enormous popularity of Q himself!
