The Minty, Snowy, and Goldie Adventure series takes a turn with Book 7, The Rose Queen. With elements of good versus evil, class conflict, and the responsibility of wealth and power, this book takes the young heroines on a new journey. Back in Epping, Minty and Snowy are maturing toward womanhood, as Goldie, adjusting to a new life outside an orphanage, has royal dreams.

Meanwhile, Rosaleen Bramble, the royal gardener with humble Irish roots, has a knack for making plants thrive, but she's fed up with the royal family's dismissive abuse. Throughout London, the water supply has been tainted, causing illness and death. At the same time, wild rose bushes are cropping up, along with growing resentment toward the monarchy.

Snowy, Minty, and Goldie head to the Royal Observatory in Greenwich to investigate with their friends, John Flamsteed, Christopher Wren, and the Duke of Somerset. Rosaleen plots to eliminate the spoiled aristocrats and will stop at nothing to gain revenge. Can Minty, Snowy, and Goldie nip her evil plans in the bud before they bloom?
