The third book of In Our Shadow, by kitfox-crimson, also known as Matt Cleaver.
Madagascar has been destroyed, and with it, almost the entire lemur race. On the moon, one of the fabled neural flares - sources of ultimate knowledge - has been found and used by Bray. This has put Australia in the firing line of the next rat annihilation fleet. While Bray, Pipa and Lady Brushfire attempt to make defensive plans against the rat attack, Amethyst and Brianna set off for the recentlty damaged twilight shroud pylon. They hope to find a weakness in it and discover the shroud’s original purpose; knowledge that will be invaluable against the incoming rat threat.
