Illegal Alien by Robert J. Sawyer and similar items

Science Fiction. Hardback, excellent condition other than some yellowing of dust jacket. Combine with other items from me to save on shipping. "When a disabled starship enters the Earth's atmosphere, fear is quickly replaced with awe. The first contact ever between humans and aliens is made. Seven incredibly intelligent members of the Tosok race are welcomed by the world with open arms. In exchange for the resources and help to repair their ship, they offer to share their knowledge and technology. But, as the people of the Earth put their best faces forward, the growing sense of trust is shattered. A popular scientist, part of the aliens' traveling entourage, is found dead - mutilated and dismembered by a mysterious weapon. All evidence points to one of the Tosoks."
