Book Description
Do you know silica, the tetrahedra of silicon and oxygen constituting the crystals of New Agers and the desiccant in a box of new shoes? It's no mere mundane mineral. As chemically reacting silicate rocks, silica set off the chain of events known as the origin of life. As biomineralized opal, it is the cell wall, skeleton, spicules, and scales of organisms ornamenting numerous lobes of the tree of life. Cryptocrystalline silica made into stone tools helped drive the evolution of our hands and our capability for complex grammar, music, and mathematics. As quartz crystals, silica is impressively electric and ubiquitous in modern technology (think sonar, radios, telephones, ultrasound, and cheap but precise watches). Silica is inescapable when we take a drink or mow the lawn and it has already started to save the Earth from the carbon dioxide we're spewing into the atmosphere. This book tells these scientific tales and more, to give dear, modest silica its due.

Book Description
Sarah is growing up fast. She swings on swings, slides down slides, and climbs trees. Whenever she falls, her mother sweeps her up in her arms and soothes away the hurt. Her mother is always there for her-on her first day of school, when she falls in love for the first time, and finally when she leaves home and starts a family of her own. It is then that Sarah realizes what a wonderful gift her mother has given her. As she watches over a daughter of her own, Sarah passes on that gift, helping her child through the trials of growing up with a gentle strength and enduring love. This beautiful testament to the powerful bond between mothers and daughters will move and inspire mothers while reassuring their daughters that they have a special safety net that will never let them down. Anna Strauss was only sixteen-years-old when she was inspired to write this story as a gift for her mother. Now her enchanting story makes a perfect gift to celebrate the special mother/daughter bond on Mother's Day, Graduation Day, and all year round.
