Everyone was dead. Indian raiders massacred the entire wagon train. Only seven-year-old Hardy Collins and three-year-old Betty Sue Powell, managed to survive. With a knife, a faithful stallion, and the survival lessons his father taught him, Hardy must face the challenges of the open prairie as they head west in search of help. Using ingenuity and common sense, Hardy builds shelters, forages for food, and learns to care for Betty Sue. But their journey through this hostile wilderness is being tracked by even more hostile men. And, as he struggles to keep them alive, Hardy realizes that their survival may depend on his ability to go far beyond what his father had been able to teach him.

ルイ・ラムールが描く本作は、西部劇の枠を超えた「過酷な環境における魂の継承」の物語です。七歳の少年が広大な荒野に放り出される絶望的な状況。そこには、父から授かった知恵と、恐怖を凌駕する生存本能のせめぎ合いが綴られています。子供という無垢な視点から荒野の残酷さを描き出す筆致は、読者に真の勇気とは何かを強烈に問いかけます。 映像化作品では圧倒的な景観が目を引きますが、原作の醍醐味は少年の克明な内面描写にあります。父の教えを超えて自らの意志で困難を突破する瞬間の心理的躍動は、活字を通じてのみ深く魂に刻まれるでしょう。視覚的な緊張感と文学的な深みが呼応し合うことで、物語は不朽のサバイバル神話へと昇華されています。
