Time on the Harbour

By Graham Bottomley

"Time-traveling teens alter their grandfather's past and must break into a WWII Naval Base to save him from a deadly Japanese submarine attack on Sydney Harbour before it erases their own future."

Time on the Harbour delivers sci-fi thrills, romance, and adventure as late-teen siblings Mark and Gemma Bentley are thrust into 1942 Sydney, Australia. A reckless time-travel slip has put their grandfather, Kevin, on a doomed troop ship destined to be torpedoed by a Japanese submarine.

​Desperate to save him and preserve their future, Mark and Gemma kidnap Kevin, pleading with him to stay off the ship. Kevin, thinking they're out of their minds, slips from their grasp and boards the ship.

​Now, the siblings face a heart-pounding mission: infiltrate a heavily guarded Naval Base to rescue Kevin before the deadly strike. Time on the Harbour sweeps readers into a wartime world of sacrifice, family, and life-altering choices.
