Turn Talk Into Action is a best-selling leadership guide for anyone tired of meetings that go nowhere. In a world of hybrid work and constant change, leaders must design conversations that create energy, inclusion, and measurable outcomes.

Drawing on behavioural science and real-world experience with over 500 leaders and boards, Dr Isabella Allan shows how to transform meetings from echo chambers into spaces of curiosity, challenge, and collaboration.

Through her practical four stages of dialogue framework, readers learn how to engage every voice, surface better decisions, and turn discussion into momentum.

Packed with proven tactics, scenarios, and design tools, this book is an executive library essential for leaders who want their meetings, and their people, to matter.

Most leaders don’t fear change — they fear uncertainty.

Complexity Anxiety: Leading Beyond Fear explores the discomfort, confusion, and cognitive overload that arise when familiar patterns break down.

Drawing on her PhD research into surprise and decision-making and two decades of leadership work, Dr Isabella Allan reveals why uncertainty triggers anxiety in organisations, and how that anxiety quietly shapes culture, communication, and strategic paralysis.

Through stories, simulation insights, and practical reflection tools, Complexity Anxiety helps leaders recognise their own responses to surprise — and turn those moments of discomfort into opportunities for clarity, learning, and adaptive leadership.

Complexity isn’t just something to think through, it’s something to perceive.

SENSATE: The art of perception in a complex world explores how leaders can refine their perception to navigate uncertainty with clarity and composure. Moving beyond the five senses, it introduces the emotional, relational, and systemic awareness that complex environments demand.

Drawing on decades of work with executives and organisations under pressure, Dr Isabella Allan reveals how perception, pattern recognition, and empathy combine to create clarity in chaos.

Through compelling insights and reflective tools, SENSATE invites readers to practise the art of perception, to see the unseen, sense what matters, and turn noise into meaning.

In complexity, the hardest part isn’t choosing sides. it’s learning to hold them.

AND: Problem Solving in a time of complexity is a manifesto for leaders who know that progress lives in the tension between opposites. Drawing on her work with executives and boards navigating disruption, Dr Isabella Allan explores how the most effective leaders integrate confidence and doubt, speed and reflection, stability and change.

Through powerful ideas and grounded examples, AND challenges the illusion of balance and invites leaders to think, decide, and act from the space in between.

Short enough to read in one sitting, yet rich enough to shift a career, AND is a manifesto for a new kind of leadership, one that turns paradox into possibility.

Uncertainty is now a constant, but how we navigate it determines whether we survive or thrive.

NAVIGATE: Thriving in times of complexity, explores what it takes for leaders and organisations to stay steady, adaptable, and purposeful when conditions are anything but. Drawing on her work across sectors and decades of research into leadership in complexity, Dr Isabella Allan introduces practical ways to build confidence, connection, and clarity under pressure.

From cultivating resilience to strengthening trust and decision-making, NAVIGATE helps readers turn turbulence into traction. It’s a book about moving forward when the map keeps changing, and discovering the mindset that allows leaders not just to cope with complexity, but to thrive within it.
