"Raintree Freestyle" is a range of non-fiction books for the less able or reluctant reader aged between 11 and 14 years. Designed for students with a reading age of 8 and 9 years, these books should enable readers to encounter curriculum-linked topics at an appropriate reading level. The "Out There?" thread enters a world of weird and unexplained events, both famous and less well known. The series looks at aliens, UFOs, monsters, ghosts and other unexplained phenomena. Strange and frightening tales are told, various explanations are examined, and each title ends with an open question that leads readers to make their own minds up.
