All sorts of names are given to us vets by people: cow doctor, dog doctor, horse doctor… But I’m a fish doctor—and I’ve almost gotten used to it. Still, when there’s a chance to get a little rest from the endless medical routine, I try to take advantage of it. Hunting for a beast that’s almost unknown to science—at the edge of explored space—that’s just the kind of case. Find it, sedate it, package it in a reliable cage, and deliver it to a zoo—on paper, everything is always simple. But as usual, only in words… This is the FIRST book of the cycle, but there’s also a story that’s where it all began.
