I see from this review by Claire Perkins that Elizabeth Grosz has two recent books dealing with metaphysics (ontology) nature and life ---Time Travels, which draws together eight years worth of essays that I have previously mentioned in this post and Nick of Time, which I have yet to read. The latter seems to be more centrally concened with nature and life as becoming.

Perkins says that the figures across the books, and the books themselves, are linked by the motivation to recognise the full force of temporality in relation to life:

Given Deleuze's own sustained engagements with both Nietzsche and Bergson it is perhaps not surprising to find these as two of the figures whose understanding of temporality is here central to a practical ontology of becoming. The figure who stands out across the two books is Darwin, although what Grosz is ultimately drawing out in her engagement with his work is what Deleuze (with Guattari) also notices, namely just how nomadic Darwin's contributions to an understanding of life are.

Perkins says that in the Nick of TimeGrosz engages in a self-critique whilst developing an ontology of becoming through exploring the practical implications for living beings of their immersion in the continuous forward movement of time.

The explicit link that Grosz makes here is to the body. The ontology of life that she draws out in Darwin impels an understanding of bodies as beings that are foremost temporal, rather than spatial. In this movement Grosz readily acknowledges the ways in which she is moving beyond the relationship between biology and culture she has worked with previously. What she is also moving beyond, of course, is the still influential strangle-hold that psychoanalysis has on the biology-culture model. The biological body is here explored neither as a passive receiver of cultural inscription, nor as an "alien" force which inhibits such inscription, but as an interactive surface which gives itself up to cultural location
