The fourth exciting entry in Rick Riordan's best-selling Heroes of Olympus series is now a graphic novel!

At the conclusion of The Mark of Athena, Annabeth and Percy tumble into a pit leading straight to the Underworld. The other five demigods have to put aside their grief and follow Percy's instructions to find the mortal side of the Doors of Death. If they can fight their way through the Gaea's forces, and Percy and Annabeth can survive the House of Hades, then the Seven will be able to seal the Doors from both sides and prevent the giants from raising Gaea. But, Leo wonders, if the Doors are sealed, how will Percy and Annabeth be able to escape?

They have no choice. If the demigods don't succeed, Gaea's armies will never die. They have no time. In about a month, the Romans will march on Camp Half-Blood. The stakes are higher than ever in this adventure that dives into the depths of Tartarus.

Helped to improve combustion in 12 year old Mercruiser 3.0L engine
Color: Blue, Number of Items: 1
I used the whole bottle in 1/2 tank of questionable gasoline from used boat from dealership, with no idea what mixture of gas water and particulates was in the gas tank in this 12 year old boat. The dealer started up the boat, and it was taking a minute to get the idle going. He mentioned that the gas was a few months old, but I am guessing that is was more like 6 months old. This is the TKS engine, self priming. I think some water / condensate was in the tank. Before taking out to first trip, I added bottle and 5 gallons fresh gas. That trip to the lake, I still has some issues getting it to start easily. Ran OK, not great that day, went home, changed cap and rotor and wires. Next trip, 1 week later, the 3.0L started great, ran great, I am not sure if it took some hours to fully mix and interact with the old gas, neutralize the water, and perform it's reactions, before it made existing gas more combustible, but that is what it seemed like to me. ***UPDATE**** - I had strange fuel issues the next season after using this product. I had to replace the fuel pump and many other fuel delivery components including the carburetor. Not sure if this contributed to the fuel system failing, the long term effects outweigh the short term gains.
