It is dark on the river. The fog is thick. The moon is high. Get on the Night Ship. The Night Ship is a low level phonics reading book. Beautifully illustrated throughout, this 205-word fiction story features a fully decodable text, suitable for ages 9 - 13. The Night Ship covers the second set of basic letters and sounds that students meet in Phase 3 of Letters and Sounds, the UK Government's synthetic phonics reading programme. The Night Ship is part of Ransom Reading Stars Plus, a structured reading programme for students learning to read.

The series has ten levels: four phonics levels (covering Letters and Sounds Phases 2 to 5) and six book bands (Pink through to Orange).
