A guide to the hand-gun
Walter Winans was an acknowledged expert on the subject of firearms and shooting of all kinds in the early years of the 20th century and his comprehensive guides to the subject are well known and highly regarded. In this book he explains the evolution of the revolver and the selection of the right pistol to suit an individual. He provides here a guide to ammunition and to the care, cleaning, maintenance and use of a pistol before turning his attention to the many applications of the hand-gun in shooting sports. He also discusses duelling, the art of shooting while riding on horseback and the use of hand held firearms in wartime. When this book was first published the hand-gun was evolving and the familiar cylindrical chamber was being superseded by automatic mechanisms. Automatic pistols were increasingly produced and adopted by service personnel and this aspect of shooting is also briefly covered. This is an ideal companion for sports shooters, those who fire historical weapons, re-enactors, modellers, firearm collectors and others.

Murder most fowl? In this sardonic and campy YA thriller, an anxious, introverted nonbinary teen birder somehow finds themself investigating a murder with their neighbor/fellow anime lover, all while falling for a cute girl from their birding group...and trying not to get killed next.  Sixteen-year-old Bianca Torre is an avid birder undergoing a gender identity crisis and grappling with an ever-growing list of fears. Some, like Fear #6: Initiating Conversation, keep them constrained, forcing them to watch birds from the telescope in their bedroom. And, occasionally, their neighbors. When their gaze wanders to one particular window across the street, Bianca witnesses a creepy plague-masked murderer take their neighbor’s life. Worse, the death is ruled a suicide, forcing Bianca to make a choice—succumb to their long list of fears (including #3 Murder and #55 Breaking into a Dead Guy’s Apartment), or investigate what happened.  Bianca enlists the help of their friend Anderson Coleman, but the two have more knowledge of anime than true crime. As Bianca and Anderson dig deeper into the murder with a little help from Bianca’s crush and fellow birding aficionado, Elaine Yee (#13 Beautiful People, #11 Parents Discovering They’re a Raging Lesbian), the trio uncover a conspiracy much larger—and weirder—than imagined. And when the killer catches wind of the investigation, suddenly Bianca’s #1 fear of public speaking doesn’t sound so bad compared to the threat of being silenced for good. In this absurdist, darkly comical YA thriller that is a deceptively deep exploration of anxiety and identity, perhaps the real murder investigation is the friends we make along the way. 

The Otherwoods is calling. And it won't be ignored. Some would call River Rydell a 'chosen one': born with the ability to see monsters and travel to a terrifying spirit world called The Otherwoods, they have all the makings of a hero. But River just calls themself unlucky. After all, it's not like anyone actually believes River can see these things-or that anyone even believes monsters exist in the first place. So the way River sees it, it's better to keep their head down and ignore anything Otherwoods related. But The Otherwoods won't be ignored any longer. When River's only friend (and crush) Avery is kidnapped and dragged into The Otherwoods by monsters, River has no choice but to confront the world they've seen only in their nightmares-but reality turns out be more horrifying than they could have ever imagined. With only their cat for protection and a wayward teen spirit as their guide, River must face the monsters of The Otherwoods and their own fears to save Avery and become the hero they were (unfortunately) destined to be. Justine Pucella Winans will have you cowering and cackling as you follow River's reluctant hero's journey, perfect for fans of Doll Bones, Ghost Squad, and Too Bright to See.
