The authors are the husband and wife team that so successfully recreated the life story of Joy and George Adamson and their Elsa in the movie Born Free. During the ten and a half months of filming, they kept a journal and a photographic record of their experiences set down here in a slender book that may capture a portion of that movie's audience. It was a question of courage, of facing up to a big lion's bear hug in an attempt to establish the same rapport that the Adamsons had achieved. And when you're playing with semi-wild Kenya cats, the game can be dangerous...as ""Ginny"" discovered one broken leg too late. There are moments of high tension and high comedy as the couple learns to ""share life,"" with Boy, Girl, Mara, little Elsa, Spotty and Big Boy. The book manages to communicate the personalities of the animals so well that the epilogue is doubly sad; most of their friends are now permanently in cages. A little book, tender and touching.
