Thirty-somethings Lewis and Wren fall in love in a promising meet cute as he endures a bad date with someone else and she watches and eavesdrops upon it all unfolding. Idealistic Lewis is an aspiring actor and playwright turned teacher, and careful Wren, born to a teenage single mother, works in finance for stability and security. In due course, Wren and Lewis get married, and like any couple, they share and grow together while keeping some thoughts to themselves. 

The “normal” trajectory of their relationship is interrupted by a startling diagnosis: A Carcharodon carcharias mutation has befallen Lewis, causing him to transform into a great white shark before their first anniversary. As her new husband morphs more and more rapidly, Wren buys scuba equipment and installs an aboveground pool. Lewis eats cans of tuna and boiled shrimp around the clock while still trying to teach and write for as long as he can.

The knowledge of their imminent separation forces decisions and conversations they didn’t plan to tackle so early in their marriage. As Shark Heart winds through both their pasts (Wren’s especially), poignant and meaningful moments abound as they search their memories and experiences to help them navigate an uncertain future. 

Debut novelist Emily Habeck has crafted a story that is surprisingly moving, oddly heartwarming and deeply contemplative beyond its tragicomic premise. Habeck, who has a background in theater and theology, has a real dramatic flair, capturing her characters’ conflicts and buried longings in the face of undesired transformation. The “ever illusory margin between human and animal” is a key element of the novel’s world, one where people can become pregnant with birds or turn into zebras or Komodo dragons.

The short chapters and stylistic changes (some sections are formatted with only dialogue, while others are just a few sentences) do occasionally distract, but the depth of visceral emotion helps offset any affectation. Interspersed with Wren and Lewis’ story is the history of Wren’s mother, Angela, revealing much about who Wren is and why this parting with Lewis is so hard for her. 

This story of love and connection—between mother and daughter, husband and wife, and friends that are like family—vividly explores both the fragility and tenacity of humanity. Shark Heart’s questions are universal: How do we let go of the ones we love? How do we move on after loss? And how do we—can we—open ourselves up to joy again? Like Wren, we survive, exist and begin again in the “terrifying and sublime journey” that is life.

Time travel narratives are so ubiquitous in our culture that we all must have, at some point, considered what it would be like to go back in time. Not just to remember, but to actually go back—to observe our parents when they were young, to take fresh note of textures and colors and shapes and situations and emotions we didn’t notice or understand when we were children. In Edan Lepucki’s novel Time’s Mouth, a grandmother and granddaughter share this ability, which is as much an affliction as it is a blessing.

Born in 1938, Sharon begins to “transport” when she’s a teenager, shortly after the death of her despised, abusive father. She leaves home, takes on the name Ursa and moves into a creaky mansion hidden away in a redwood forest. There she comes to govern a weird hippie commune populated by broken women, each given the honorific of “mama,” and their children.

The children’s lives swing between a sort of indentured servitude and a not-so-benign neglect. With the exception of Ursa’s son, Ray, none of the children are allowed to go to school or see a doctor, lest their existence be discovered. But Ray’s privilege is Ursa’s mistake. His knowledge of the outside world lets him see how twisted this village of mamas is. He and his secret girlfriend, Cherry, escape, but Cherry leaves him when their daughter, Opal, is just a baby. Inevitably, Opal, who inherits her grandmother’s fantastic gift, wants to know why.

This gift is tangled up with each woman’s experiences of motherhood and daughterhood, going back generations. Ursa leaves behind her own mother who refused to protect her, then later transports to reclaim Ray, and Opal uses her powers to learn more about her own absent mother. But even mothers who are present aren’t necessarily good enough, as is seen in the commune’s derelict mamas. 

Ursa is Latin for “bear,” and mama bears are famous for being fiercely protective of their cubs. But Lepucki’s Ursa is more fierce than protective. She is, to be blunt, a psychopath. She has no use for the nonservile; her love is conditional, if not transactional; and if she’s thwarted, she reacts with mind-bending violence.

The bestselling author of Woman No. 17 and California, Lepucki displays a real talent for giving readers a new perspective—whether on the passions of motherhood in particular, or on the nature of parenthood in general—and emphasizes the power of real love (and a bit of New Agey therapy) to heal.
