Best sellers and high rating pictures have brought My Friend, Flicka and Thunderhead before a very wide audience. That market is a dependable bet for the third of the series, third and probably the last (though we hope Miss O'Hara will go on writing horse stories and stories of Wyoming for a long, long time). In this tale, young Ken, boy hero of all three books, wins his heart's desire, and at the end after many heartaches and adventures on route, he has his beloved Thunderhead back on the ranch, a champion, accepted by Rob McLaughlin as fit successor of the ageing Banner, as stud for the stables. Thunderhead has had two years of freedom, freedom on the range, freedom to steal mares from surrounding ranches- and distant ones as well-, freedom to win his mead of fame and infamy. Ken has broken his heart, known fear, met failure- but at the end he wins Thunderhead back. Meantime, he has found another love in Carey, girl owner of the English thorobred filly, whose dramatic loss and subsequent capture by Thunderhead for his band brought about the organized search which comprises a large part of the story. There is in the story adventure of the search, of the wilds, of failure and success. There's the round of life in the new west, of ranches and animals. And against it all is the family story of the McLaughlins, the sense of self-searching, as two boys grow to young manhood, and Nell finds in spiritual strength, the security she needed. A book that conservatives will like and that will interest all ages.
