" An adventure featuring Patrick Troughton's second incarnation of the Doctor that's so faithful to the era it even thoughtfully includes whole episodes worth of unnecessary padding (Jamie and some kids escape to a moon, mostly so that they can gad about a bit and come back). The Doctor is reasonably portrayed, and his companions Jamie and Zoe are particularly well captured and expanded on. The yarn itself rattles along pleasantly despite several random acts of repetition (numerous expeditions to the same place and back to pick up extra bits of information - one would possibly have done). Baxter gives sound science, and his wheel in space is a very credible technological wonder, but the base under siege hijinks fizzle out with a damp squib of an ending that isn't clever enough to make confounding the reader's expectations worthwhile. A mixed bag then, but an affectionate and entertaining one. "
