Seacrest Siblings Books in Order

The Seacrest Siblings books show a different side of Catherine Coles. Instead of historical murder, these stories lean into contemporary romance and family drama, with hospital corridors, foster care decisions, and difficult home lives doing much of the emotional work. The pace is quieter, but the stakes are still high, because the questions at the center are about children, trust, responsibility, and whether damaged people can build something steady together.

The danger here is emotional rather than murderous.

Duty of Care gives the clearest picture of the world. Penny Miller is a foster carer who knows, from her own past, what it means to feel unwanted. When a baby girl arrives at Seacrest Hospital without the safe start she deserves, Penny is determined to protect her. That puts her on a collision course with consultant paediatrician Adam Reynolds, the baby's uncle, who believes family should mean he gets to take over. It is a strong setup because nobody is wrong in a simple way. Both characters are trying to do right, and that makes the romance harder, messier, and more believable.

That seems to be the real pull of these books. They care about what people do when duty and feeling start pulling in different directions. Work matters. Background matters. Childhood experience matters. The adults in these stories often look capable from the outside, but they are carrying old hurts, private guilt, or the sense that they have spent years being useful without ever feeling fully secure. Coles writes that kind of tension in a straightforward way, which keeps the emotion grounded.

Alongside Doctor Behind the Mask, these books sit in the same general neighborhood. They point to Coles's wider interest in medical settings and in the gap between the professional face someone shows the world and the more vulnerable person underneath. That makes them a good fit for readers who like relationship stories with real practical pressure around them, not just attraction in a vacuum.

Family is the big theme that links everything. Not perfect family. Not easy family. The sort of family people lose, search for, make, or fight to protect. Children are not background props, and caring work is never treated as simple. That gives the books a softer, more earnest feel than the mystery series, while still keeping plenty of tension on the page.

If you are coming to Catherine Coles for cozy murder, this corner of her work will feel different. If you want a warmer, more contemporary story about care, love, and the hard work of building a home, that difference is exactly the point.
