Stella, Olivia, And Beatrix: SmallPowers Book Five

The sister of Bella, one of the nameless order's most powerful and successful wizards, and one of their two mothers, take their non-mage friend on a fieldtrip across several universes to an ancient world of druids. Beatrix is no mage, but she is too clever by ten halves and a bucket of steel ball bearings. A complex tale of magic and mystery that introduces several new characters and their back-stories in the SmallPowers series that all radiate out from a world no one knew was or is in dire peril. The end of a world can start at the beginning. Or perhaps, even before the beginning.

Book five of the SmallPowers saga.
