Malcolm, Callie & Keira Books in Order

Susan Mallery's Malcolm, Callie, and Keira stories follow members of the Carlesso family as they learn what it means to belong to one another. When We Found Home brings three half siblings together after very different childhoods, while It Started One Christmas returns to Keira for a romance of her own. The connection is a newly formed family, rather than a long-running town where a succession of unrelated couples takes the lead.

Malcolm has grown up with the family's resources and now carries substantial responsibilities in its food business. Callie and Keira have not had the same security or experience of home. When their grandfather brings them into the family, sharing a father gives them a reason to live together, but it does not give them a shared history or an automatic understanding of each other's fears.

Their Seattle home puts the contrast between material comfort and emotional safety into focus. Malcolm is used to solving business problems, yet his sisters need more than efficient arrangements. Callie must decide how much trust she can place in an unexpected welcome, while younger Keira is still learning whether the adults around her will remain dependable when things become difficult.

Romance widens that story of connection. Malcolm's relationship with Delaney Holbrook introduces another person whose life has taken an unexpected turn, and the family's attempts to help one another cannot remain separate from their individual choices. The novel makes room for the awkwardness of becoming siblings as adults or near strangers, including the misunderstandings that good intentions alone do not prevent.

Being offered a home is only the start of feeling at home.

It Started One Christmas shifts the attention to Keira and Dalton, a scientist without a home for the holidays. When she welcomes him in, an act of kindness develops into friendship and then a possible romance. The Christmas setting gives the story a gentler focus on hospitality, companionship, and the ways an encounter can become important before either person has planned for it, while retaining the family connection established in the earlier novel.

Read When We Found Home first to meet Malcolm, Callie, and Keira and understand the relationships behind the holiday story. Then follow it with It Started One Christmas for Keira's later romantic focus. The tone combines family fiction with romance and hopeful new beginnings, with room for painful backgrounds and uncertainty about trust. Readers who enjoy found-family stories will recognize the central idea: relatives may be linked by blood, but the work of becoming a family depends on patience, choices, and the willingness to make space for someone else's needs.
