I read this as a scanned paperback copy on the Internet Archive. Published in 1977, it's a sequel to the author's "Crash Landing on Iduna" which was one of the early offerings in Harlequin's short-lived Laser Books line. In the first book, the Everson family escapes an overcrowded and polluted Earth and travels through space looking to find a new home. Their ship crashes on a planet they name Iduna, and the five family members establish a bucolic Swiss-Family-Robinson-style existence. In this sequel, years have passed when a ship from Earth unexpectedly arrives in space over Iduna, loaded with a desparate group of government officials. Conditions on Earth have deteriorated even further and those in power have fled to Iduna where they intend to establish a colony. The newcomers clash with the Eversons, and by means too complicated to describe in this review, three of the family and two defecting crewmen hijack the newly-arrived starship and make the 6-month voyage back to Earth. There they find chaos - food supplies have completely run out and billions are starving and turning to violence and savagery. Cannibalism is rumored. So after barely a day on Earth, they turn right back around and make the 6-month return trip to Iduna. They arrive barely ahead of 3 additional ships that have fled from Earth with the remaining top government officials. Things are getting crowded for the Eversons. I doubt that anyone who might read this review will then be interested in reading the book, but I won't give any further spoilers as to how it all ends. The book is a short read at less than 200 pages. The story had some odd juxtapositions. There are rhapsodic descriptions of the peace and beauty of Iduna, but there is also a surprising amount of violence. Many, many people are burned to cinders with laser rifles, crushed under the treads of tanks, or beaten to death, but it's all described non-graphically. The whole book seemed off-kilter. Looking through the listing of the author's other books, it doesn't appear there's a third entry in the series, and that's probably a good thing. Three out of five stars.
