Here is a consolidated overview of reviews from major journals and other sources:
Participation in God by Andrew Davison — Review Overview
Cambridge University Press, 2019 (published 2020). xii + 423 pp.
Academic Journal Reviews
Journal of Theological Studies (Richard Cross, Vol. 72/1, April 2021)
Cross describes it as an ambitious book that amounts “more or less to a complete systematic theology structured around the organizing notion of participation,” situating Davison in the loosely Thomistic tradition associated with figures like David Burrell.  Cross singles out Chapter 6 as perhaps the best, noting that Davison provides a “very helpful and judicious” account of the foundational participation-relation: the participant has not a part of what is participated, but a part in what is participated. 
Scottish Journal of Theology (Anthony Baker, Vol. 74/3, August 2021)
Baker’s verdict is that “few scholars have the gift of writing such a full treatment of a bedrock idea in a way that is both approachable and generative of new critical engagement. Davison has this gift, and he has written such a book.” 
Modern Theology (Simon Oliver, Vol. 37/2, 2021)
Oliver calls it “a magnificent gift to teachers and students of Christian theology, preachers of the faith, spiritual directors of the faithful, and specialists requiring a systematic theology of participation.” 
International Philosophical Quarterly (Vol. 60/3, September 2020)
This review highlights Davison’s engagement with different Christian traditions, arguing that his comprehensive participatory view renders “certain divisive doctrinal measures unnecessary,” and commends the book’s scholarly depth and suitability for a range of academic contexts. 
The Living Church (Daria Spezzano)
Spezzano writes that Davison “offers an impressive and wide-ranging study of the doctrine of participation, effectively demonstrating how it provides a metaphysical framework for theology that allows us to see the world as a gift from God, bearing some trace of his likeness, and creation as profoundly precious because of the one who gives it to us.” 
Extended Academic Review (Academia.edu, penultimate draft)
One reviewer notes that Davison “succeeds overall in offering a clear, theologically nuanced and philosophically tenable articulation of participation in God,” and remarks that while works of this kind can be opaque, “Davison’s monograph stands out since he writes for the specialist and the nonspecialist alike.” 
The reviewer also notes that Davison is careful to navigate the risk of pantheism and vague interpretations of “participation” that might obscure meaningful metaphysical distinctions, doing so by clearly articulating the metaphysical character of participation across various theological themes, including divine causation and its Aristotelian/Neoplatonic background via Aquinas. 
Evangelical Blog Review (Andrew Fuller Blog, 2020)
This reviewer, writing from an evangelical perspective, finds Davison’s passion and vision for recovering participatory language “contagious,” particularly his emphasis on participation in terms of intimacy, relationship, and fellowship, and concludes that his own “view of salvation and communion has been forever altered.” 
The same reviewer offers the most substantive criticism: Davison’s greatest weakness was his lack of contemporary analysis on the importance of participatory ontology for twenty-first-century North American evangelicalism — a cultural-anthropological and sociological account of the state of the Church would have been helpful. 
Reader Reception (Goodreads)
Reader responses range from describing it as “one of the most important foundational books concerning theological metaphysics” and “paradigm-shifting” to calling it outright “magnificent.” Several readers place it among the best theological books they have read, though some note modest reservations regarding the application of participation to soteriology. 
Summary Assessment
The consensus across reviewers is that Participation in God is a landmark achievement — unusually comprehensive, accessible without sacrificing rigor, and constructive across doctrinal loci (creation, Christology, epistemology, ethics, ecclesiology). The main critical notes touch on: (1) the book’s Thomistic-Anglican center of gravity leaving some traditions underserved; (2) limited engagement with contemporary evangelical or North American ecclesial contexts; and (3) occasional questions about the soteriological application of participatory categories. For your work in the Nee-Lee tradition, Davison’s treatment of creation as continuous dependence, knowing as participatory, and the transcendentals (truth, beauty, goodness) as loci of participation would be the most dialogically productive entry points.
