A dark, dazzling, tragi-comic tale of childhood wonder, time-travelling poets and theoretical physics -- joint winner of the inaugural Terry Pratchett Prize. On the eve of Granny Hazel's burial in the back garden, a stranger in his time machine -- a machine that bears an uncanny resemblance to a Morris Minor -- visits five year-old Edward with a strange request. And Edward agrees to be his friend. But Edward is not alone in the world. His twin sister Sophia is about to bring future tragedy upon herself through an all-too-literal misunderstanding of a promise she's made to their father. So while Sophia stays at home, seemingly condemned to spend the rest of her days in The Manse -- a world untouched by modern trappings -- Edward is sent to boarding school. There he encounters the kind and the not-so-kind, and meets the strangest child. His name is Alf, and Alf is a boy whose very existence would seem to hint at universes of unlimited possibilities... and who might one day help Edward liberate Sophia. With its Gothic backdrop, Half-Sick of Shadows is a novel of many parts: at once a comical tragedy, a dark and dazzlingly told tale of childhood wonder and dismay, of familial dysfunction, of poetry, the imagination and theoretical physics.

Half Sick of Shadows

When Goose's parents are killed in a car crash on Christmas Eve, his life changes utterly. Living with his increasingly senile Nan, his dog Mutt is the only thing keeping him sane. His only other friend is Frank, a former friend of his father. Frank's own life is falling apart and he has recruited Goose to help him carry out petty theft around the city. A year to the day since the accident that changed his life, Goose meets Anthony, a strange man who has forgotten who he is, but seems to know more about others than they know about themselves. When Mutt goes missing, Goose has no choice but to rely on Anthony to help find him. In an adventure that draws in Frank, who's lost his family, an old lady who's lost a precious bangle, an elderly doctor who's lost his wife and mother who's lost her daughter, Goose follows Anthony across Manchester. But at the centre of the mystery is Anthony himself: who is he, how does he know so much and can he help Goose and the others find what they're searching for? A delight to read from start to finish, David Logan takes the reader on a terrific journey through love, loss and the quest for home.

Junk's sister has been stolen. Snatched from her bed in the dead of night, Ambeline doesn't stand a chance. No one believes Junk saw a monster take his sister. No one believes he's not to blame.

His journey will take him to a future world where animal species have evolved, and where the cult of the League of Sharks - the cult that stole Junk's sister - is etched into folklore...

The League of Sharks

This textbook is for the standard, one-semester, junior-senior course that often goes by the title "Elementary Partial Differential Equations" or "Boundary Value Problems". The audience consists of students in mathematics, engineering, and the sciences. The topics include derivations of some of the standard models of mathematical physics and methods for solving those equations on unbounded and bounded domains, and applications of PDE's to biology. The text differs from other texts in its brevity; yet it provides coverage of the main topics usually studied in the standard course, as well as an introduction to using computer algebra packages to solve and understand partial differential equations. For the 3rd edition the section on numerical methods has been considerably expanded to reflect their central role in PDE's. A treatment of the finite element method has been included and the code for numerical calculations is now written for MATLAB. Nonetheless the brevity of the text has been maintained. To further aid the reader in mastering the material and using the book, the clarity of the exercises has been improved, more routine exercises have been included, and the entire text has been visually reformatted to improve readability.

Applied Partial Differential Equations

Goose is lost. It's Christmas, his parents are dead and now his dog Mutt has gone missing. Those around him aren't doing much better: his uncle Frank's wife has walked out, and his nan is losing her mind. But then Anthony appears - a man who seems to know everything about those he meets, but nothing at all about himself. Who is he, how does he know so much, and can he help Goose and the others recover what they've lost? So begins a dramatic adventure through love, loss and the quest for home.
