"A thrill ride across space and time." R.A. Jones The Thief of Two Worlds, introduces us to Caleb and Veyda McGreggor, a brother and sister who join their father and an alien from Alpha Centauri to capture an intergalactic, power mad thief. This unusual pairing of humans and aliens team up to time-jump into earth's past to help track and capture the renegade who has stolen the greatest treasure of the planet Tugz, "The Egg"! On their Angkor Wat adventure they cross paths with -- a rogue elephant, a ruthless "bird god", Kai the Tiger Killer, and...Albert Einstein!! They meet every challenge with intelligence, faith, courage, and metallic crabs called Twydddle! The Thief of Two Worlds! connects with readers in their everyday life as they discover how twelve year old Caleb learns science cannot solve every problem, and his ten year old Christian sister, Veyda, gains understanding in how overcome fear with faith. Educator Nancy Carlson writes: Vance has skillfully crafted a Christian science fiction tale. Young people will be captivated by this story that begins with an alien enlisting the help of scientist-inventor Jon McGreggor to travel to 12th century Cambodia. There's just one problem---his children are stowaways which adds an unexpected ingredient to the mission. I highly recommend this book which grapples with faith and fear along the way.
