Wow! This is a very passionate and beautiful work, with soaring lines, very French, in a style somewhere between Fauré and Franck. In the new Chandos recording it is coupled with Fauré's 2nd Violin Sonata, Renaldo Hahn's Violin Sonata and a Nocturne by Lili Boulanger.
Here's an appreciative review:

It's such an attractive selection of pieces, and such a warm endorsement, that I am almost persuaded to 'double-up' on my existing versions. The rediscovery of the music of Mel Bonis is a joy to behold!
