Alan Dean Foster's
For Love of Mother Not is $.99 (from $6.99) at
Kobo and
Amazon.
This is book 1 of the
Flinx and Pip series and was one of my favorite dog-eared paperbacks when I was younger. I haven't read it in twenty-five years or so, though, so I guess I'll have to read it again to see how much my tastes have changed.
Edit: Also at
Barnes & Noble now, which is apparently a little slow on the uptake.
