Kat and Aunt Jessie visit Renaissance Italy with their time machine, where Kat and her friend, a would-be artist, inadvertently become involved in a plot to steal notebooks from Leonardo da Vinci.

A raspberry-blowing, skateboarding ape, dodgy politicians, glamorous much-married mayor, gay ex-rugby player, teenage hoodies, a charismatic police inspector for love interest, third-rate mobsters, and a mariachi band from Bognor. A laugh-aloud book whose opening sets the story off on a trajectory of bizarre characters and quirky humour. Movie buff and community rights worker Kat Shakespeare is one heart-pounding step from insolvency when she lands a contract to troubleshoot a housing makeover project, but when a skeleton is discovered under a demolished tower block she turns detective, determined to both bring in the project on time and solve a thirty-year-old mystery.

When rehearsing her role in a wedding keeps her from enjoying tournament preparations, ten-year-old Princess Alissa turns to magic, but a love spell goes awry, throwing the entire kingdom into an uproar and endangering lives, including that of the groom-to-be.

Junior high is where things really start to happen. Cliques form and break apart. Couples are made and destroyed. And a reputation is solidified that you won’t ever be able to escape. Everything you do and say, and everyone you spend your time with, matters. Katie Mills knows that. She gets it. That’s why she tried so hard to get in with the cool girls at school. And why she was so devastated when those efforts found her detained for shoplifting and laughed out of cheer squad tryouts. But Katie has more to worry about than just fitting in. Her parents are divorced and always fighting. Her sister never has time for her. And her friends all seem to be drifting apart. Even worse? The boy she has a crush on is dating the mean girl at school. Everything is a mess, and Katie doesn’t feel like she has control over any of it. Certainly not over her weight, which has always topped out at slightly pudgier than normal—at least, according to her mother. So when she happens to catch one of the popular girls throwing up in the bathroom one day, it sparks an idea. A match that quickly engulfs her life in flames. Is there any going back once she gets started down this path? And would she even want to if she could?

​​​​In the spring of 1976, George Andrews of Pennsylvania State University visited the library at Trinity College, Cambridge, to examine the papers of the late G.N. Watson. Among these papers, Andrews discovered a sheaf of 138 pages in the handwriting of Srinivasa Ramanujan. This manuscript was soon designated, "Ramanujan's lost notebook." Its discovery has frequently been deemed the mathematical equivalent of finding Beethoven's tenth symphony. This volume is the fourth of five volumes that the authors plan to write on Ramanujan’s lost notebook.​ In contrast to the first three books on Ramanujan's Lost Notebook, the fourth book does not focus on q-series. Most of the entries examined in this volume fall under the purviews of number theory and classical analysis. Several incomplete manuscripts of Ramanujan published by Narosa with the lost notebook are discussed. Three of the partial manuscripts are on diophantine approximation, and others are in classical Fourier analysis and prime number theory. Most of the entries in number theory fall under the umbrella of classical analytic number theory. Perhaps the most intriguing entries are connected with the classical, unsolved circle and divisor problems. Review from the second volume: "Fans of Ramanujan's mathematics are sure to be delighted by this book. While some of the content is taken directly from published papers, most chapters contain new material and some previously published proofs have been improved. Many entries are just begging for further study and will undoubtedly be inspiring research for decades to come. The next installment in this series is eagerly awaited." - MathSciNet Review from the first volume: "Andrews and Berndt are to be congratulated on the job they are doing. This is the first step...on the way to an understanding of the work of the genius Ramanujan. It should act as an inspiration to future generations of mathematicians to tackle a job that will never be complete." - Gazette of the Australian Mathematical Society​
