The Island - Adrian McKinty

IT WAS JUST SUPPOSED TO BE A FAMILY VACATION.
A TERRIBLE ACCIDENT CHANGED EVERYTHING.
YOU DON'T KNOW WHAT YOU'RE CAPABLE OF UNTIL THEY COME FOR YOUR FAMILY.

After moving from a small country town to Seattle, Heather Baxter marries Tom, a widowed doctor with a young son and teenage daughter. A working vacation overseas seems like the perfect way to bring the new family together, but once they’re deep in the Australian outback, the jet-lagged and exhausted kids are so over their new mom.
