Book #5 in the Barsoom series.

Impetuous and headstrong is Tara, Princess of Helium and daughter of John Carter. Tara meets Prince Gahan of Gathol, and is initially unimpressed, viewing him as something of a popinjay. Later she takes her flier into a storm and loses control of the craft, and the storm carries her to an unfamiliar region of Barsoom. After landing and fleeing from a pack of ferocious Banths, she is captured by the horrific Kaldanes, who resemble large heads with small, crab-like legs, and John Carter must race to save her.
