The House of Hades (The Heroes of Olympus #4)

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 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.

The Lightning Thief (Percy Jackson and the Olympians #1)

Percy Jackson is about to be kicked out of boarding school... again. And that's the least of his troubles. Lately, mythological monsters and the gods of Mount Olympus seem to be walking straight out of the pages of Percy's Greek mythology textbook and into his life. And worse, he's angered a few of them. Zeus' master lightning bolt has been stolen, and Percy is the prime suspect.

Now Percy and his friends have just ten days to find and return Zeus' stolen property and bring peace to a warring Mount Olympus. But to succeed on his quest, Percy will have to do more than catch the true thief: he must come to terms with the father who abandoned him; solve the riddle of the Oracle, which warns him of betrayal by a friend; and unravel a treachery more powerful than the gods themselves.

Tres Navarre has just hours of apprenticeship time to serve before he can go for his P.I. license. Staking out a musician suspected of stealing a demo tape should be a piece of pan dulce. But his attention wanders just long enough for fiddle player Julie Kearnes to be gunned down before his eyes.

The missing demo and Julie's murder are just two of the problems besetting Miranda Daniels, a pint-sized singer with Texas-sized talent.

The Last King of Texas (Tres Navarre #3)

Multiple-award-winning author Rick Riordan brings back smart-mouthed Texas P.I. Tres Navarre for his most dangerous case yet. If you think the academic world is deadly dull, you're half right....

When a controversial English professor is found shot to death, Tres Navarre — P.I. and Ph.D. — is the only local academic crazy enough to accept the emergency opening at the University of Texas at San Antonio. Police assure him they already have a suspect, so while they wrap up the open-and-shut case, all Tres has to do is teach three classes, grade on a curve ... and walk in a dead man's shoes.

It should be an easy assignment — but one thing Tres doesn't do is easy. When the evidence in the case starts looking a little too perfect, when the killing doesn't stop, Tres takes on some extracurricular research into the heart of an assassin — and lands in a high-stakes game of gangster honor on the darkest streets of San Antonio's West Side....
