The amazing sequel to World of Fire. Dev Harmer has landed in a new body on a new planet. He has gills and fins and a chronic malfunction in his genes. With only 72 hours to bring the settlers and natives of a colonised world to peace before his temporary body expires, murder and corruption are the least of his worries. With the indigenous 'mer-folk' on the seabed and the human settlers in floating cities on the ocean surface cannibalising the mer-tech in an attempt to force their way into the eco-system, Harmer is in a race against the clock to ensure his mission doesn't end in abject disaster, a Polis+ coup or genocide.
