The Ugly Little Boy
Published in the UK as Child of Time.
To the astounded world of contemporary Earth, he is a beast, a Neanderthal ape-boy torn from the primordial past. But to his nurse and protector, he is something much more than a time-travel experiment. Edith Fellowes took the job with Stasis Technologies with the understanding that the nursing job would definitely be temporary... but all that changed upon meeting Timmie, the lonely boy whose every friend and relative — even his whole race — was 40,000 years dead.
Then Edith Fellowes discovers the scientists' true intentions, and she forms a bizarre and daring plan. At stake is Timmie's very existence... and her own.
