An important innovator in the action-adventure genre, H. Rider Haggard didn't rest on his laurels after creating an immensely popular series based around gentleman explorer Allan Quatermain. Instead, Haggard continued to push the genre forward—sometimes by harking to the ancient past. In the novel Eric Brighteyes, Haggard borrows heavily from Norse mythology, setting a classic action-adventure tale in the land now known as Iceland.
