A Pirate's Gem for Ri

In search of pirate treasure, two siblings will face danger that could end their sea-faring days forever.

Life on the high seas has been a thrilling adventure for Clif and Ri. With their new two-ship fleet, the siblings set off to find the legendary Gemstone Islands-a bounty so dangerous, not even the fearsome Stormrider will seek it.

But with the bounty in their sights, Clif and Ri will battle storms, other pirates, and perilous locations to add to their treasure hoard. But will this high-seas adventure end up being their last or will the powerful pirate duo manage to find yet another storied treasure?
