Ultraa...Pulsar...Vanadium...Esro Brachis...Who are...the Sentinels? From the moment Lyn Li foils an attempt to kidnap her from her own college campus, she is plunged into a new world, and a new life. Working-- and battling-- alongside a brilliant inventor, a famous super hero, and an enigmatic alien powerhouse, Lyn will confront the monstrous menace of the Warlord and his minions. When at last they clash atop his vast, floating city, can the world itself survive? Equal parts old-fashioned pulp adventure, comics-style super hero action, and science fiction wonderment, SENTINELS: WHEN STRIKES THE WARLORD has something for everyone who enjoys a brisk, fast-paced journey into excitement.
