Their journey is the fillip the book needed - the pace picks up, the settings and side-characters change with a frequency that keeps the narrative moving - but it comes 100 pages too late, after a historical contextualising that the interested reader could exhume themselves from the myriad texts Ihimaera quotes.
Even the narrative strategy where Horitana's nemesis, the one-dimensional evil Pakeha genius Piharo, puts Horitana in a tangata mokomokai, a silver mask, comes from Dumas' The Man in the Iron Mask. Ihimaera references great art - the novel originated as a libretto that relocated Beethoven's Fidelio - but, if he draws inspiration from these works himself, he seems incapable - or unwilling - to pass them on to the reader via his own work in any great measure.
There are, of course, from someone of his irrefutable talent, moments of tender beauty, but his natural lyricism is stymied by using an ageing history teacher as narrator, whose deliberate ordinariness replaces Ihimaera's usually more creative voice.
Some of the musings on how history gets retold are diverting enough, but none are especially new, the author - and others - having long hewn material from the rock of oral versus written historical tradition/who owns history/what is truth, and so forth. One can only hope that Ihimaera had to get this work - and his reaction to his recent infamy - out of his system and that, duly freed up, he can return to the fine writing and imaginative narratives for which he first made his mark.
