There is never a dull moment at Sparrow Crest Academy!  In the past few months they’ve been dealing with aggressive plastic army men, monster sized hamsters, and even a mummy! Recently, school board member Addie Perez has proposed some renovations to the school’s historic astronomy tower.   But Poppi Chase, a Sparrow Crest Junior and founder of the TPL (Tower Preservation League) is convinced that Ms. Perez isn’t quite what she seems – and she’s right.  Before she knows it Poppi, her best friend Kettrick and the academy’s newest student, Mitch are caught up in an adventure that's bigger than anything they could have imagined!
