Now an active member of the resistance, Lena has transformed. The nascent rebellion has ignited into an all-out revolution, and Lena is at the center of the fight. After rescuing Julian from a death sentence, Lena and her friends fled to the Wilds. But the Wilds are no longer a safe haven.

As Lena navigates the increasingly dangerous terrain of the Wilds, her best friend, Hana, lives a safe, loveless life in Portland as the fiancée of the young mayor. They live side by side in a world that divides them until, at last, their stories converge.

Poor Inspector Gallagher -- his premonition was right. Sister Mary Helen is once more in the middle of a homicide case. Not that she wants to be. No one would envy the poor nun, who finds herself holding a dying young woman -- shot to death in the street almost directly outside the Refuge for homeless women where Mary Helen volunteers. And even while she grieves over the loss of life, Mary Helen spots something odd about the victim. Although she is wearing near-rags, her skin is unblemished and healthy-looking. Her perfect teeth are white and unstained. She doesn't look like a woman whose life has been spent in poverty, in the streets. Mary Helen's feeling is borne out when she discovers that the dead woman was a Vice Department officer trying to find the people responsible for a neighborhood prostitute ring. And in spite of her own conscience warning her, the old nun feels that since the murder happened in front of HER refuge, it is her duty to find the officer's killer. She justifies this by telling herself that her connections with the women who use the Refuge put her in a unique position to get some inside information about what is going on in their neighborhood. After all, isn't one of the Refuge's very own women, Geraldine, the aunt of Junior Johnson? And isn't Junior just about the most powerful and knowledgeable man in the 'hood? So Sister Mary Helen plunges in, determined to find Sarah Spencer's killer. Her "invasion" of the case enrages Inspector Gallagher, but if she is to succeed, his further fury will be well worth Mary Helen's triumph. The police officers assigned to the crimes that turn out to be "hers" might make a case that someone Mary Helen's age is running a serious risk when she deals with criminals and their world. But the delightful old nun has the weapons of her logical mind, and her determination. And just maybe Someone whom she serves is rooting for her. In any case, she is able to work out of perilous situations, come up with commonsense answers, and gather a huge circle of loving fans as she meddles in murder.

A tale of secrets and miracles

"Malvinas Requiem has a well-earned spot as the major literary piece on Argentina's only twentieth-century war."--Buenos Aires Herald It's early June 1982 and winter in the Falkland Islands: twenty-four young soldiers--deserters from the Argentine army--spend the last weeks of the conflict hiding underground in a cave. Inside their refuge, they listen to the radio, stockpile supplies, and exchange stories; outside, under cover of night, they trade with the Argentine quartermaster and with the British. Looking out over the bleak landscape, after weeks of gray skies and horizontal snow, one of them remarks that "you'd have to be English to want this."

Sister Mary Helen is sinfully good at snooping through the San Francisco fog. Now a fellow OWL (Older Woman's League) member has disappeared. The police believe Erma Duran simply flew the coop, but Sister feels a Higher Authority pushing her to investigate. A gold medal entangled in Erma's bedsprings and a cryptic clue to a Byzantine madonna deepens the mystery. By the time Police Inspector Kate Murphy joins the hunt, Sister's good intentions have already paved her way straight to the Mission District--and a hellish encounter with sudden death.

Sister Mary Helen and her Irish friend, Sister Eileen, need some R&R away from the pressures of their inner city vocation. A week at the idyllic St. Colette's Retreat House, snuggled amid towering redwoods 65 miles from San Francisco, sounds like heaven. Unfortunately the muddled sisters mistakenly arrive a week too early and find that St. Colette's is hosting a convention of hard drinking, high spirited priests. And when the serenity is further shattered by the murder of a former seminary student, suspicion falls on the holy fathers. But Sister Mary Helen has another theory about the perpetrator, and in her inimitable way she intends to uncover the deadly secrets and passions that the flesh is heir to...
