We Are Tam — Patricia Bernard

Tam's ordinary school day explodes when a voice inside her head sings her name. The voice belongs to Tameron--a mirror-image twin living five hundred years in the future whose brilliant father is dying. Only Tam and her sceptical brother Steven can bridge the centuries, decode a forbidden time-capsule and out-run giant snow-white mosquitoes that freeze history itself.We Are Tam is a fast-paced, middle-grade adventure packed with telepathic twists, brother-sister banter and big questions about why the past matters. Perfect for readers who loved A Wrinkle in Time and When You Reach Me.
