'In a desperate race against the Dark, Maerad must try to solve the final riddle of the Treesong. Only then will the Nameless One be defeated and peace restored to the Seven Kingdoms. But Maerad only holds the key to half the riddle - her long-lost brother, Hem, has the other.

'Before embarking on a perilous journey to find Hem, Maerad must first wage an epic war against the Landrost. And Hem, fleeing the advances of the Black Army, must endure betrayal and mortal illness in his search for Maerad.

'But the Dark grows ever more powerful - will brother and sister reach one another in time or will all be lost in a final, apocalyptic battle?' (Publisher's blurb)

'Whilst his sister, Maerad, pursues her dangerous destiny in the frozen North, Hem is sent south to Turbansk for his own safety. But soon the forces of the Dark overrun the great city and Hem flees with his mentor, Saliman, his white crow, Irc, and a young orphan girl, Zelika, to join the resistance. He agrees to help fight the Nameless One by spying on the child armies of the Dark. Now Hem has a vision – he too has a part to play in Maerad's quest for the Treesong. But Zelika has been captured by the child army, and Hem's destiny must wait. Hem pursues Zelika to the Dark's stronghold, little realizing that her cause is lost. He reunites with Saliman and, broken-hearted, starts the perilous search for his sister.'

'Alexandre Lourenço recounts his daring adventures with his older brother, the inventor Bartolomeu, aboard their wildly innovative airship, the Passarola, or "great bird." After finding rich patrons in Lisbon to fund Bartolomeu's flight obsession, they make their successful maiden voyage on the vacuum-pumped Passarola in 1731 in the presence of His Majesty João V. However, the brothers run afoul of Cardinal Conti's Inquisition and flee to France, where they are championed by the Enlightenment regime of Louis XV, as long as their airship can serve his purposes. Commissioned by the Académie des Sciences to measure distances to the polar circle, the brothers set out on a harrowing trek into the extreme northern regions, where Alex is beset by hallucinations of a splendid phantom city, and they must turn back. They cannot offer indisputable proof of what they saw during their exploration, so, disheartened they separate—Alex back to Brazil, to lead a mediocre existence, and Bartolomeu off to incredible adventures in India and beyond.'
