With each new dawn, the celestial body known only as 'Calamity' draws closer - and with it the end of the world. Humanity's only hope from oblivion rests in the menhirs, towering bastions of scholarship and imagination which cast long shadows across the lands. The scholars within the menhirs devote themselves selflessly to the discovery of new magic that will help avert the impending apocalypse ... or so the masses have been made to understand.

In a society divided between those with occult potential and lay citizens, Tara Langcraw is recruited into the Amber Menhir with great interest. The long-awaited heiress of a bloodline bearing the rarest of the six magical disciplines, time manipulation, she is expected to flourish within this noble citadel of learning, as are her friends and fellow recruits, Roland Ward and Peony Bianchi.

They soon find, however, that those who fail to meet expectations, or who dare to challenge the prevailing order, put more than their marks on the line. For the menhir squirms with rivalries, and those who stand against the status quo may not stand for very long.
