Blades of Mars

Michael Kane, Earthman, had to return to Mars - to Vashu. He had no choice. He had left his heart there, with the lovely Queen Shizala, and on his home planet he found nothing but loneliness. No one knew better than he the dangers involved in stepping into the matter transmitter again. It might send him anywhere, anywhen...The one thing he did not anticipate was that it would send him to Mars, but a Mars vastly different from the one he had known. From his arrival on, he found himself embroiled in a series of hair-raising adventures that led him inexorably to the obsidian city populated by the strange spidermen. And his flashing blade was his only defense against perils stranger than he - or any human - had ever encountered.
