The Harmony Hourglass — Tyler H. Jolley

For the first time since Alison Liv Isner started her adventures, she's not eager for the next one. After conquering her previous expeditions in Honduras, Egypt, Transylvania, and Nepal, she fears there aren't many left in her mom's journal. And while she loves the adventures, she loves being with her friends even more. She's already lost her mom -- losing her last connection to her mom would be devastating!

While Ali and her friends have been training and working hard to perfect their adventuring skills, so have the Geese. With each expedition the Geese have become more brazen and aggressive. Ali and her friends must recover the Harmony Hourglass before the Geese can pillage, plunder, and loot it and all the innocent people of Port Cartagena de Indias.

With the stakes at an all-time high and the pressure mounting, Ali knows she must succeed -- but will this be her last adventure?
