The Doctor is back in the lives of Grant, Lucy, and their
daughter, Jennifer! He’s on a mission to find the other three alien gemstones,
siblings of the one that gave Grant his superheroic powers – and only Grant can
lead the way! Following the gems’ trail through time, the four ended up in a
future New York City ruled by the fearsome entity known as THE SMOKE – and
reclaimed one gem. They set off in the TARDIS and arrived at their next
destination... a world where the Harmony Shoal has taken over! But Grant’s
powers have ceased working – just as he and the Doctor are in the direst of
straits!
