Tom and Jack Gargarin are inseparable. They love model aeroplanes and they miss their dad, who might have been left behind on a space mission to the moon. They're building a rocket to bring him back safely. But something is desperately wrong. In the hot summer of 1971, a world of Russian cosmonauts and tiny Lancaster bombers, spies and secrets, the Cold War and telly dinners, Tom and Jack must examine all the evidence to find the heart of a dark truth. At once very funny and totally heartbreaking, this unique book takes us inside a mind spiraling into insanity and brings us to a truly shocking conclusion.
