Published Jan. 12, 1985 by Del Rey.
When a one-way time tunnel to Earth's distant past, specifically six million B.C., was discovered by folks on the Galactic Milieu, every misfit for light-years around hurried to pass through it. Each sought his own brand of happiness. But none could have guessed what awaited them. Not even in a million years....
Has lasted well, probably I first read this 30 years ago. A bit uneven in tone at times, but a good adventure. Will now have to set aside time to re-read the others!
